From Thermal City to Well-Being Landscape: A Proposal for the UNESCO Heritage Site of Pineta Park in Montecatini Terme

Abstract

Thermal cities represent a valuable example of cultural heritage as an expression of territorial relationships, reflecting the interplay between the physical characteristics of the landscape and human creativity. Their cultural value was recognized with the inscription of 11 spa towns in the UNESCO World Heritage List in 2021. However, since the late 20th century, shifting economic and social conditions have led to a widespread crisis in thermal tourism, resulting in abandonment and degradation. So far, this issue has been primarily addressed through tourism and economic models, largely neglecting the landscape perspective. This article, instead, argues that a landscape-based approach is essential for understanding the complexity of the problem and for providing sustainable solutions. The paper seeks to answer two research questions: (i) the first concerns the role of landscape design within the conservation framework of thermal heritage; (ii) the second addresses the creation of new values and opportunities, investigating how landscape design can support a sustainable and context-sensitive transformation of thermal cities. The study adopts the Research-through-Design (RTD) methodology and takes advantage of the landscape design proposal developed for Montecatini Terme, in Italy, as an opportunity to explore the broader issue of rethinking traditional spa towns in crisis. As a result of this design and research experience, it is argued that landscape design plays a crucial role in establishing an integrated system capable of supporting the sustainable development of spa towns and recommendations for decision-makers are provided.

1. Introduction

1.1. Spa Towns and Well-Being Landscapes

The relationship between cities, landscape, and well-being has deep historical roots and is closely intertwined with the element of water [1]. Indeed, since ancient times, water has supported functions related to hygiene, self-care, and health at both individual and societal scales [2,3]. Traces of the use of water for therapeutic purposes can be found as early as prehistoric times and across various civilizations, giving rise to diverse practices such as the hammam tradition of the Orient, the Japanese onsen, and the sauna/banya in Scandinavia and Russia. In Europe, this tradition evolved into the spa phenomenon [4]. Medicinal mineral water is defined by the World Health Organization (WHO) as “water bacteriologically uncontaminated that proceeds from a natural or perforated subterranean source and that contains a determined mineralization that can induce favourable health effects”. Since antiquity, some benefits of mineral waters have been intuitively recognized, later supported by advances in knowledge and scientific discoveries. To summarize the historical development of the spa culture in Europe, it is relevant to point out that the origin of thermalism as a social and economic phenomenon can be traced back to the Roman Imperial Era, when attendance at thermal baths became a widespread social practice [5]. Even the origin of the term spa is believed to be the Latin sparsa fontana (“gushing fountain”) or, alternatively, sanitas per aquas (“health through water”). The Romans recognized the curative and recreational value of natural thermal springs, sometimes appreciated for their temperature (naturally warm waters) or for their properties (nitrous waters valued for their intestinal benefits and sulphurous waters for their effects on the skin), as reported by several ancient authors, such as Vitruvius and Pliny the Elder [6,7,8,9]. Following the fall of the Roman Empire, thermal culture declined during the Middle Ages, due to political and religious factors. However, thermal traditions persisted in the Byzantine Empire, developing unique characteristics that were later reintroduced to Europe through Arab influence. The Renaissance marked a gradual rediscovery of thermal practices, and the first systemic attempts to study the curative properties of mineral waters date back to this period. Among these is the treatise entitled Balneorum Italiae proprietatibus (1417) by Ugolino da Montecatini, a pioneer of medical hydrology, which was followed by numerous other studies mainly in Italy and England [4]. By the 18th century, spa culture began to consolidate its scientific foundations, leading to an increasing number of studies on the biological and therapeutic effects of mineral waters [10]. During this period, particularly between 1720 and 1780, the city of Bath, UK, became a centre of research thanks to the studies of Dr. George Cheyne, who investigated the properties of Bath’s mineral waters in his book Observations Concerning the Nature and due Method of Treating the Gout (1720), and others, including Dr. Rice Charlton, who developed numerical analyses to assess the effectiveness of different treatments. From 1800 onwards, the scientific basis of thermal medicine was consolidated and further enriched by the fundamental contributions of other European scholars, such as the Swedish chemist Jöns Jacob Berzelius and the Bohemian physicists Josef Loeschner and Eduard Hlawaczek, who mainly studied balneotherapy [11]. Prompted by a growing awareness of public health issues, thermal centres were gradually transformed into holiday destinations and hubs of social life, acquiring a distinct touristic identity [12].

Thus, the spa phenomenon is closely connected to architecture, with the construction of monumental thermal complexes, to urban planning, shaping spa towns with specific features, and to landscape design, integrating the benefits of thermal treatments with the immersive and contemplative experience of natural settings [13]. Consequently, numerous spa towns emerged across Europe, structured around thermal practices and tourism as their core identity and economic foundation.

In tracing the development of modern thermal tourism, Urošević highlighted the role of a coordinated transport network, which initially concentrated this phenomenon in the highly industrialized and urbanized areas of Western Europe [14]. For instance, the railway connection between Paris and Nice, established in 1864, significantly contributed to the subsequent development of the Côte d’Azur. Similarly, the city of Montecatini Terme, in Italy, which is the case study of this research, was reached by the railway in 1857 and since then has developed as a spa centre connected with the other main cities in Tuscany.

The development of thermalism in Europe led to a widespread cultural phenomenon, manifesting in similar and recognizable characteristics across different European countries, despite local specificities. Peter Borsay emphasized the high degree of similarity among spa towns: while reference models evolved over time and new trends emerged, a resort culture developed, sharing many common elements, such as the search for health and the pursuit of nature, sociability, status acquisition, and class assertion [15].

This layered and complex cultural phenomenon has produced recognizable and valuable heritage expressions in spa towns, spanning from the landscape scale to the architectural features of thermal buildings [16]. The architectural historian Francois Loyer defined spa towns as “authentic laboratories for experimental architecture, whose integrity should be protected”. To understand spa towns, it is useful to refer to the concept of “therapeutic landscapes”, developed by Gesler in 1992 to investigate the healing dimensions of specific sites [17]. Recognizing that the “healing process works itself out in places (or situations, locales, settings and milieus)”, Gesler highlighted that the connection between place and well-being is expressed through a multitude of elements, including natural components, such as plants, parks, and water, and underlined the role of natural environment when it intersects with the social environment [18,19]. The concept of therapeutic landscape thus refers to a broader notion of well-being, which is not just biomedical health [20,21]. Spa towns across Europe perfectly embraced this concept by developing urban settings with the primary vocation of thermal care, but also enhancing the aesthetic, recreational, and social value of natural environments and leisure activities.

The recognition of this homogeneous cultural system led the United Nations Educational, Scientific and Cultural Organization (UNESCO) to approve the nomination of 11 European spa towns across seven countries for inscription on the World Heritage List as the “Great Spa Towns of Europe” in 2021 [22]. However, several spa towns today face significant challenges, due to the decline of thermalism as it was understood in the 20th century, the impacts of economic crises and the effects of COVID-19, the limitations of being single-industry cities, and other structural issues. These challenges have contributed to a widespread perception of stagnation or decline. This paper argues that a landscape and territorial perspective is essential for understanding the complexity of the challenges faced by spa towns and that landscape design can serve as a catalyst for sustainable development processes. The research is based on the experience developed by the authors for the redesign of the park of Montecatini Terme, developed for the City of Montecatini Terme and Fodazione Caript.

The article is structured into five sections. This Section 1 provides an introduction to the European spa phenomenon and its cultural significance. This is followed by an overview of the key challenges faced by spa towns today. Section 2 outlines the research objectives, research questions, and methodology applied in this study. Section 3 introduces the case study, describing both the European framework of UNESCO-listed spa towns and the specific case of Montecatini Terme. Section 4 presents the design and planning work carried out in the case study. Section 5 critically discusses the knowledge generated through this design experience and its relevance to the broader discourse on the enhancement and revitalization of spa towns.

1.2. Evolution and Current Challenges of Spa Towns

Thermal practices have experienced alternating fortunes since antiquity, with periods of splendour followed by centuries of neglect. In order to understand the present moment, it is relevant to examine the development of modern thermalism over the last century and a half. In fact, it was from the 18th century onwards that renewed attention to public health and advances in the medical sciences stimulated systematic study and promotion of the benefits associated with thermal practices [12]. However, it was not until the late 19th century that thermalism emerged as a tourism phenomenon.

Referring to the periodization proposed by Becheri for thermalism in Italy, different phases can be identified in the development of thermal culture, which can—with some adjustments—be extended to a similar evolution in Europe [23]. The first phase can be defined as “Ludic Thermalism” and developed between 1890 and 1930. In this phase, thermalism was approached by an aristocratic elite. The second phase is that of “Social Thermalism”, spanning from the post-war period to the mid-1970s, when thermal baths became a mass social phenomenon accessible to a wide public. The third phase described by Becheri is specifically related to the Italian context, where, in the 1970s and 1980s, “Assisted Thermalism” developed: during this period, public health policies supported widely accessible mass treatments, and, as a result, the revenues of the thermal system depended almost exclusively on the national health system, placing the thermal economy out of the market [24]. The medicalization of thermal treatments and state intervention in the thermal economy were observed approximately in the same years in other European countries, such as France, where the Sécurité Sociale reimbursed three-week standard thermal treatment periods [12,25], and England, where the funding for free spa treatment promoted by the National Health Service in 1948 was later withdrawn due to the impact of new drug regimens and financial pressures [26]. From a medical perspective, the benefits of thermal treatments, which were intuitively known since ancient times, can be categorized into three main areas: the treatment of musculoskeletal disorders, respiratory diseases, and digestive system disorders [27]. Depending on the properties of different springs, thermal establishments and spa towns specialize in specific treatments and applications, ranging from traditional balneotherapy to mud therapy and hydropinic treatments (i.e., drinking thermal waters). For example, in the case of Montecatini Terme (Italy), which will be further analysed in this article, the presence of acidulous saline waters (rich in chloride–sulfate, magnesium, and sodium bicarbonate) has shaped its thermal practice, primarily focusing on hydropinic treatments for liver, kidney, digestive, and urinary disorders [28]. From the 1980s, in response to the changing political and economic climate, public subsidies for thermal treatments began to be limited, leading to a gradual crisis in the sector. Across Europe, by the late 21st century, thermal tourism had reached a point of maturity. This resulted in either stagnation or a decline in visitor numbers, creating a widespread sense of crisis and a nostalgic perception of a lost golden age.

In the new millennium, the concept of thermalism has shifted its focus from health treatment to a wider concept of well-being, introducing a set of functional services aimed at creating conditions for holistic physical and mental wellness [29,30]. To describe this process, Becheri refers to a fourth phase of thermal activity, integrating thermalism and wellness. However, the full realization of this new approach to thermalism requires a rethinking of traditional spa destinations, integrating them into a modern tourism system. This shift aligns with new wellness trends that combine healthy nutrition, physical exercise, relaxation, and cultural activities [31].

Looking at the European landscape, some cases of successful renewal can be identified. For example, the French city of Vichy established itself under Napoleon III in the second half of the 19th century and during the Belle Époque as a preferred thermal destination of excellence [11]. Its geographical location facilitated the arrival of aristocratic tourists from Paris, as well as French military and civilian personnel from the colonies. However, the city’s reputation suffered a collapse when Vichy became the seat of the collaborationist government after the German occupation in 1940 [32]. Additionally, the thermal economy was severely damaged by the end of the French colonial empire, which had a significant impact on visitor numbers. After the war, the revival of Vichy included, on the one hand, a drastic attempt to erase that problematic historical period [33], and, on the other, a continuous process of diversifying its tourism offerings. To attract a more mixed clientele throughout the year, Vichy developed itself as a venue for conventions and congresses, hosted at the Palais des Congrès, which opened in 1995 within the Grand Casino, and launched extensive promotional campaigns to position itself as a sports tourism destination. Furthermore, the city strengthened the industrial production and export of bottled mineral water, which, while linked to Vichy’s thermal tradition, became a separate core business, distinct from traditional spa and bathing tourism. However, the urban renewal initiated in the 1970s and 1980s also led to large-scale demolitions and reconstructions. This triggered the need for serious heritage protection policies. The implementation of the ZPPAUP (Zone for the Protection of Urban and Landscape Architectural Heritage) made it possible to identify exceptional buildings for the first time and to establish initial regulations for safeguarding, conserving, and enhancing heritage [34,35]. This legislative tool later evolved into the AVAP (Architecture and Heritage Development Area), a more detailed classification that included greater environmental considerations, launched in 2014 and implemented in March 2019.

Another interesting case is that of Bath, in the UK. The city’s reputation as a healing place consolidated through centuries, taking advantage of the natural setting and leveraging the symbolic power of water and architecture [36]. However, 20th-century developments threatened the urban heritage of the spa town. The city suffered significant damage from bombings during World War II, and, in the 1960s and 1970s, uncontrolled industrial and residential development took place. A period of severe economic crisis followed the closure of the major thermal baths at the end of the 1970s. In defence of its heritage, the city began to implement a systematic strategy to protect and enhance its architectural assets and cultural identity [11]. The city’s cultural value was recognized twice by UNESCO—first in 1987, when Bath was inscribed on the World Heritage List, and again in 2021, when it was included in the transnational listing of the Great Spa Towns of Europe [37]. The historian Peter Borsay observes that the city has successfully consolidated a strong historical identity and has been able to reinterpret its past and “recycle the image of the earlier period” [5]. Recently, the city has regained momentum with significant investments and a coordinated program of urban regeneration that allowed the reopening of the historic thermal baths: in 2005, an extensive restoration and modernization project was launched, including the creation of the Thermae Bath Spa, designed by Nicholas Grimshaw, and in 2009, a major urban mobility project was initiated, integrating electric public transport. These projects were framed within a city-wide vision, Future for Bath (2006), which laid the foundations for an economic redevelopment aligned with the city’s cultural identity [38,39].

In Italy, as well, some thermal destinations have attempted to relaunch themselves through large investments and ambitious architectural projects, with more uncertain results. This is the case of San Pellegrino Terme. This spa town declined after World War II, and most of its thermal facilities were progressively abandoned: the Grand Hotel closed in 1979 due to high management costs, the funicular built in 1909 to connect to the panoramic viewpoint was shut down in 1989, and the historic thermal establishment stopped working in 2006 [31]. In 2007, Lombardy Region, Bergamo Province, and Grupo Percassi launched a EUR 150 million rehabilitation project. Two years later, an international architectural competition was held, awarding the project of Dominique Perrault, which aimed to create a new luxury thermal centre inspired by the Dolomites’ rocky landscape [40,41]. Despite its interesting approach to modernizing the town while respecting its historic landscape, the project proved to be excessively ambitious and disproportionate to the actual capabilities of the municipality. In fact, construction never began, and the project was ultimately abandoned. In 2014, thermal activity returned to San Pellegrino thanks to new investments and the QC Group, but not in its original location; instead, it was moved to a renovated and expanded former thermal hotel. In 2016, a new competition was awarded to the Bjarke Ingels Group (BIG) for the renovation of the San Pellegrino bottling plant and surrounding urban spaces. The project is currently underway and is expected to be completed by 2029.

The mentioned cases highlight the importance of a comprehensive vision, effectively articulated through a landscape-based approach. The territorial protection measures and systemic heritage conservation strategies implemented in Bath and Vichy have successfully and coherently supported their revitalization processes, reinforced by appropriate commercial and promotional policies. In contrast, where investments are concentrated but lack an overarching strategic framework, as in the case of San Pellegrino, the outcomes remain highly uncertain. The latter case further underscores the necessity of aligning investments, commitments, and objectives with the actual capacities of spa towns facing a critical phase in their tourism economy.

2. Objective and Methodology

Acknowledging the complex and rich background of thermal culture in Europe, as well as the ongoing decline and common challenges faced by many spa towns, this article investigates the role of landscape design in redefining and supporting a sustainable path for thermal cities. To date, research on spa towns has mainly adopted an economic approach, focusing on the analysis of tourism dynamics [30,39,42], while landscape and territorial perspectives on the opportunities and challenges of these places remain largely underexplored. The European Commission also encourages a territorial approach to local development [43,44], yet applied research in this field remains limited. The mentioned cases of Bath and Vichy demonstrate an emerging awareness of this perspective. Additionally, previous attempts to apply a landscape-based approach in the context of heritage conservation conflicts should be mentioned [45], along with the studies of Fabi, Vettori, and Faroldi, who advocate for a place-based approach to reframe spa towns as strategic resources in the construction of territorial capital [38].

Building on this line of research, this paper seeks to answer two key research questions:

• What is the value of a landscape and territorial approach in safeguarding the tangible and intangible heritage of thermal cities?
• How can landscape design support a sustainable, compatible, and context-sensitive transformation of thermal cities?

The study presented in this paper centres on the case of Montecatini Terme and introduces the design experience developed by the authors, offering insights relevant to similar cases. Referring to the methodology of Research through Design (RTD), in which the designing activity is employed as a research method [46], we used the practical experience developed in Montecatini Terme as a chance to investigate a broader topic and produce knowledge that serves to answer the starting research questions and that can be extended to similar cases.

RTD can be placed among the three main modes of interactions between landscape architecture and research identified by the European Council of Landscape Architecture Schools (ECLAS), namely, research on design, research for design, and research by design (or Research through Design, as it is referred to in this paper). It involves “the analysis of complex spatial strategies by producing and evaluating scenarios, making and evaluating new typologies that are based on new needs (of the public), finding solutions for a social or spatial problem” [47]. RTD refers to a particular research strategy in landscape architecture, in which the design process is conducted in a well-considered manner to achieve a particular goal or to address a research question [48,49]. In this framework, the design activity can be considered as a research strategy and a powerful method for generating practical–productive knowledge. As noted by Nijhuis and de Vries, in order to be considered a reliable and consistent research method, the design process should be carried out in a methodical way [48]. In particular, the process should start with a design problem and the clear statement of research questions; then, the search associated with a design process is articulated into the three phases of analysis, synthesis, and evaluation; last, the design solution should be discussed and referred to the research questions stated at the beginning. The interaction of research and design results in an iterative process, in which the objective and the alternative solutions can be further refined. This approach was applied to the case study of Montecatini Terme, as shown in Figure 1.

In addition, it should be mentioned that, as a theoretical foundation for the design process, we referred to the Historic Urban Landscape (HUL) approach. This is a method of conservation in the urban development process that integrates urban conservation principles and practices into the urban development process [50]. This research adopts the definition and method of HUL proposed by UNESCO, with the intention of prioritizing the objectives of preservation and protection of material and immaterial cultural heritage, but within a dynamic vision of the urban environment responding to present and future needs [51,52]. The starting point is the recognition that a city is not a static monument or group of buildings, but is subject to dynamic forces in the economic, social, and cultural spheres that keep shaping it. The HUL is “the urban area understood as the result of a historic layering of cultural and natural values and attributes, extending beyond the notion of ‘historic centre’ or ‘ensemble’ to include the broader urban context and its geographical setting”. The innovative aspect of this approach is to coherently merge the notions of heritage and landscape, as the HUL also refers to “the site’s topography, geomorphology, hydrology and natural features, its built environment, both historic and contemporary, its infrastructures above and below ground, its open spaces and gardens, its land use patterns and spatial organization, perceptions and visual relationships (…) and also social and cultural practices and values, economic processes and the intangible dimensions of heritage as related to diversity and identity” [53]. The HUL advocates that a historic context and new development can interact and mutually reinforce their role and meaning, and this supports the attempt to integrate new approaches, such as Green Infrastructures (GIs) and Nature-Based Solutions (NBSs) [54,55]. In this perspective, historical specificities are not a constraint but a great opportunity [56,57,58,59]. Consistence with this approach is a key aspect to be included in the evaluation phase of the design process, as will be discussed at the end of this paper.

3. The Case Study

3.1. The Great Spa Towns of Europe

The general framework for this research is provided by the international network of spa towns listed by UNESCO, in which Montecatini Terme represents the only Italian city. “The Great Spas of Europe” is a serial transnational property comprising eleven towns and cities across Europe, shown in Figure 2. Serial transnational properties are defined by UNESCO as a system “where two or more component parts are required to express the Outstanding Universal Value” [60]. This group of cities has been identified by UNESCO for the relevance of the tangible and intangible heritage connected with thermal culture and spas. The decision to pursue a group nomination for the World Heritage List is also significant, as it highlights the recognition of a shared and transnational thermal culture spread across Europe. The nomination captured “the geography of this network of water cure towns, its historical geopolitical scale, and the diversity of spa history and style” [61]. Indeed, UNESCO highlighted that “Spa towns share many attributes in common, but the ways in which these attributes are expressed in each of the eleven components varies according to a wide range of factors, for example the particular relationship of the urban form to topography and landscape” [62].

The nomination process for the Great Spa Towns of Europe began in 2011, involving a substantial mobilization of resources in each participating site to prepare the dossiers and discuss the framework for this collective candidacy. On 1 July 2014, sixteen Great Spa Towns were added to the Tentative List. Then, in May 2016, following a decision by the International Steering Group, the nomination was narrowed down to eleven towns from the original sixteen. In 2021, during the 44th session of the World Heritage Committee [63,64], the Great Spa Towns of Europe were officially inscribed on the World Heritage List, under criterion II, which recognizes an important interchange of human values over time or within a cultural area, particularly in relation to architecture, technology, monumental arts, urban planning, or landscape design, and criterion III, which requires sites to bear a unique or exceptional testimony to a cultural tradition or civilization, either living or extinct [64].

The justification for inscription produced by the committee emphasized the role of spa towns as centres of experimentation that adapted to evolving tastes and tourism demands. Additionally, the committee recognized the synergistic work of architects, designers, and landscape architects, who shaped both the built and natural environments that framed spa life. Additionally, the committee acknowledged the European spa phenomenon as a cultural testimony, reflected in the urban and landscape configuration of spa towns. As places dedicated to thermal treatments, these towns evolved over the centuries to provide a balanced combination of medical practices and leisure activities, including entertainment, social interaction, and physical exercise within an outdoor therapeutic landscape [61,65].

The ten-year period between the initiation and approval of the nomination was particularly significant for each participating city. During this time, an international network was established to promote the shared heritage of these sites and facilitate the exchange of best practices. For Montecatini Terme and other spa towns currently facing economic and tourism-related challenges, UNESCO recognition—alongside participation in this network—represents an important incentive for revitalization. The nomination process itself served as an opportunity for each town to engage in a critical reassessment of its heritage, conducting an objective analysis of both its potential and its vulnerabilities. At the administrative level, UNESCO listing required these towns to implement monitoring and reporting systems in compliance with World Heritage Committee requirements. In Montecatini Terme, a municipal office was established in 2018 to manage UNESCO-related procedures and oversee the site’s administration [66].

3.2. The Site of Montecatini Terme, Italy

As previously mentioned, the case study for this research is the city of Montecatini Terme, located in the Tuscany region, in Italy. It is a small municipality with a population of about 21,000 inhabitants. From an administrative perspective, it belongs to the province of Pistoia, while geographically, it should be framed within the landscape system of Valdinievole, which is a side valley of the Arno River basin. Montecatini’s thermal vocation has been known since Roman times, but it was toward the late 18th century that the city began to take shape as a spa town. This transformation was initiated through land reclamation projects promoted by Pietro Leopoldo, Grand Duke of Tuscany, which improved the areas of the Marsh of Fucecchio. During this period, the first nucleus of thermal baths was established. Throughout the 19th century, new water springs were progressively discovered, leading to the construction of new thermal establishments and the renovation or expansion of existing ones. Montecatini’s reputation grew rapidly, supported by the publication of scientific studies on the benefits of its mineral waters and an effective promotional campaign for its spa services [67,68,69].

To accommodate the growth of elite tourism, the city was gradually equipped with various auxiliary services, such as a theatre and a casino, as well as urban infrastructure, including tree-lined avenues and expansive green spaces. The construction of key infrastructure, such as the railway (1857), the funicular railway to the old town of Montecatini Alto (1898), and the tramway connecting Montecatini to Monsummano, Lucca, and Pistoia (1907), consolidated the city’s position as a prominent tourist destination extending well beyond the regional borders (Figure 3).

At the turn of the 19th and 20th centuries, the idea of Pineta Park emerged—an extensive green space designed for leisure and promenades, serving as a connecting element between the various thermal buildings. The park was developed at the initiative of the Società Terme, based on a design by the architect Giulio Bernardini, who served as the director of the society from 1896 to 1913. Bernardini incorporated stylistic influences and inspirations acquired during his travels to major European spa destinations, bringing them to Montecatini [72].

The green system formed by Pineta Park and the individual parks of the thermal establishments merges with the urban fabric and extends through the terraced olive groves on the slope up to the old town of Montecatini Alto [73,74]. The landscape continuity of this system has been recognized by UNESCO, and within the collective nomination of the Great Spa Towns of Europe, Montecatini has been designated as the “Garden Spa of Europe”. This recognition highlights not only the value of the individual thermal buildings but also the importance of the broader landscape system, in which green spaces and Pineta Park play a fundamental role, as represented in Figure 4.

Turning to more critical aspects, it is important to note that Montecatini’s thermal activity is primarily centred around hydropinic treatments, consisting of the oral assumption of thermal water, according to a prescribed schedule. This practice has declined in popularity and has been progressively replaced by new drugs. The specificity of the thermal offering has exacerbated and intensified the broader crisis of thermal tourism, which is also affecting other spa towns [75]. With the rise of mass tourism, Montecatini experienced a shift in its touristic model, which took place in three distinct phases. Between 1950 and 1975, there was a transition from elite tourism to mass tourism and the city, leveraging its historic tradition, and it repositioned itself in the national market as a leading spa destination. The following years, until 2000, were marked by expansion and rapid growth, but also structural changes. For instance, after 1989–1990, which marked the peak in domestic tourist arrivals and overnight stays, a downward trend began. At the same time, international tourism increased, with a turning point in 1997, when foreign visitors outnumbered Italian tourists [75]. In the new millennium, Montecatini entered a natural phase of maturity, characterized by economic stagnation and a decline in visitor numbers. The contraction has been further exacerbated by external factors, such as the growth of other spa destinations in the region, which has progressively diminished Montecatini’s relative prominence, as well as the effects of globalization on tourism demand. The tourist flows that still bring visitors to Montecatini are largely due to its proximity to major cultural destinations such as Florence, whereas the number of visitors coming specifically for thermal treatments has significantly decreased. As a result, the average length of stay has been considerably reduced, dropping from approximately a week to just 3–3.5 days over the last two decades [23].

Attempts to revitalize the city have faced numerous setbacks. As part of the new Strategic Plan, the municipal administration introduced the concept of a “thermal village”, where “not the company, but the city itself becomes the product, whose originality and uniqueness go beyond the quality and level of individual services offered” [76]. To implement this vision, the city commissioned renowned architect Massimiliano Fuksas to redesign Montecatini’s thermal services, with an urban intervention aimed at reviving the historic spa town identity. Fuksas’ project envisioned a new Montecatini as a “water village”, focusing entirely on the redevelopment of the monumental Terme Leopoldine building. However, much like what occurred in San Pellegrino, the project quickly proved disproportionate in both ambition and cost relative to the city’s actual economic and administrative capacity [77]. The most significant consequence of this failure has been the suspension of the construction site at Terme Leopoldine, leaving it completely abandoned up to the present day. Meanwhile, the broader deterioration and abandonment of Montecatini’s thermal system has continued. The Terme Torretta was temporarily converted into a nightclub before permanently closing in 2008; the Terme Tamerici is occasionally used for events, though large sections remain inaccessible due to structural damage to the roof; the Terme Excelsior is closed and unused; and the progressive decline of the city’s thermal heritage persists.

As a consequence of the bankruptcy of Società Terme, which owns almost all of the city’s thermal buildings, a judicial procedure started in 2023, and an auction is currently underway to redefine the ownership of the spa facilities. At present, the acquisition of the entire thermal system by a single investor appears unlikely, and it is more probable that individual components will be sold separately. This scenario poses significant risks to the city’s heritage, as its value, as previously discussed, lies in the interconnected system of architectural and landscape elements.

3.3. Heritage Preservation Constraints

Before discussing the proposed design intervention, it is necessary to briefly outline the multiple heritage protection constraints affecting Montecatini’s thermal district, which define the regulatory framework within which any project must operate. The study area is subject to numerous protection measures, both in relation to its architectural components and its landscape system. Heritage protection operates at multiple institutional levels, ranging from UNESCO international safeguards to national regulations and local planning policies.

Regarding the UNESCO-listed area, all eleven spa towns were required to define a core zone and a buffer zone. In Montecatini’s case, the core zone includes the spa town developed at the end of the 18th century, the old town of Montecatini Alto, and the linear connection formed by the funicular railway and its associated park. The buffer zone encompasses a wider protection area, ensuring strong connections between the nominated property and its broader urban and landscape context. UNESCO inscription also imposes additional governance requirements to ensure effective transnational coordination among the participating States Parties, as well as between regional authorities and other stakeholders. Montecatini has adopted a Property Management Plan in accordance with the governance framework for transboundary and serial nominations, as outlined in the Operational Guidelines for the Implementation of the World Heritage Convention. This management plan must align with several international policy frameworks, including the Policy Document on the Impacts of Climate Change on World Heritage Properties (2007), the Strategy for Reducing Risks from Disasters at World Heritage Properties (2007), the World Heritage Strategy for Capacity Building (2011), and the Policy for the Integration of a Sustainable Development Perspective into the Processes of the World Heritage Convention (2015). Additionally, the World Heritage Committee advocates for the application of the 2011 UNESCO Recommendation on Historic Urban Landscapes. Beyond administrative constraints, an important aspect of UNESCO’s heritage framework is that Pineta Park is designated as part of the “therapeutic and recreational thermal landscape of parks and gardens.” It forms part of the core zone, alongside areas classified as “urban ensembles” and “accommodation zones”.

At the regional and provincial levels, the main regulatory references include the Territorial Strategic Plan (PIT-PPR) of Tuscany Region [78] and the Territorial Coordination Plan (PTC) of Pistoia Province [79,80]. The PIT-PPR, approved in 2015, establishes landscape protection guidelines and provides a comprehensive interpretation of regional heritage identifying different landscape units (Montecatini falls under Landscape Unit 5: “Val di Nievole and Lower Val d’Arno” [81]). The PTC further refines and regulates the landscape units within the province. Based on these guidelines, the Municipality of Montecatini has developed its urban planning instruments, including the Structural Plan (PS), approved in 2004, revised in 2012, and updated in 2024 with the inclusion of an Operational Plan, and the Urban Regulation (RU), approved in 2004 and amended in 2016 and 2022.

In summary, the thermal park area is subject to landscape protection regulations under the Italian law on cultural and environmental heritage [82]. The active protection constraints affecting the thermal park are listed below and graphically reported in Figure 5:

• Protection areas within the UNESCO-listed site (core and buffer zones) (Cultural Heritage and Landscape Code, Art. 143, c.1) [83].
• Landscape assets designated under the Cultural Heritage and Landscape Code (Art. 136) and legally protected areas such as waterways (Art. 142).
• Architectural assets under formal heritage protection orders.

The PS is particularly significant, as it also articulates the strategic vision for Montecatini’s development. Among its objectives, it emphasizes the strategic importance of rehabilitating the thermal system and Pineta Park, particularly regarding the preservation of its ecosystem structure and landscape values (Objective 2). Additionally, the PS highlights the need for heritage protection strategies to be based on a holistic understanding of Montecatini’s historic thermal heritage as an integrated system, inclusive of the thermal park (Objective 3). Furthermore, as part of its strategic actions for revitalizing the spa town, the PS underscores the necessity of redeveloping public spaces and enhancing slow mobility networks to strengthen territorial connectivity (Objective 6) and the importance of promoting Montecatini’s identity as a health-focused destination, based on a broader and more integrated vision of well-being (Objective 7).

4. Landscape Analysis

Given the complex and delicate scenario outlined so far, our design team has initiated a dialogue with the Municipality of Montecatini and Fondazione Caript to support the city during this critical transitional phase. Due to the ongoing sale of the thermal establishments, the city is currently paralyzed, awaiting the identification of the future buyer(s). For this reason, we agreed to focus on Pineta Park, which remains under public ownership, and to develop a landscape project independent of the individual architectural components. However, this intervention is intended to serve as a guiding framework for the future repurposing of the various buildings. In other words, given the current impossibility of intervening in the architectural heritage, landscape design represents the only effective tool available to the administration to shape future strategies for the thermal buildings and to preserve the idea of an interconnected heritage system. In dialogue with the Municipality of Montecatini, the proposed intervention area includes the public park, covering approximately 10 hectares, and two private areas, namely, the parks of Terme Torretta and Terme Tamerici, which significantly complement the landscape system. Our design proposal responded to the request to develop a strategic masterplan for Pineta Park as the core connecting element of the thermal system, viewing it as a valuable opportunity for reflection on the role of landscape design in the safeguarding of Historic Urban Landscapes.

The design approach is aimed at respecting and enhancing the city’s heritage, with the goal of strengthening its cultural identity. The landscape design proposal is based on an in-depth understanding of the system through historical and territorial analysis, as well as an assessment of the current state. To effectively summarize the observations made, an analysis of Strengths–Weaknesses–Opportunities–Threats (SWOT) was developed, as outlined in the following paragraphs.

4.1. Strengths

Pineta Park presents a number of valuable features, both tangible and intangible, which make it a key component of the spa town heritage. Among the main features we identified as strengths are the following:

• Central location in the heart of the city—the park’s central position enhances accessibility for both residents and visitors, contributing to its attractiveness and ease of access.
• Strategic placement of viewpoints—carefully positioned viewpoints highlight the park’s iconic landmarks and panoramic vistas, increasing its visual appeal and stimulating visitors’ imagination.
• Diverse architectural palimpsest—the park features a variety of architectural styles and structures that narrate layers of history and culture, offering visitors a fascinating journey through time and a deeper appreciation of its cultural fabric.
• Water features and thermal springs—beyond their aesthetic beauty, these natural elements provide therapeutic benefits, creating a serene and invigorating environment that enhances the overall visitor experience, making the park an ideal destination for relaxation and well-being.

4.2. Weaknesses

Despite its landscape and architectural value, the park generally suffers from a lack of maintenance and care in its management. Additionally, there is a shortage of attractive focal points and support facilities to enhance the visitor experience. Another critical issue is the legacy of a recent past in which automobiles were allowed to circulate through most of the park’s pathways, leading to extensive paving with concrete and asphalt—an intervention that is now inappropriate. Considering these aspects, the main weaknesses of the site can be summarized as follows:

• Lack of designated spaces for events—the absence of dedicated areas for cultural and musical performances limits the park’s ability to attract new visitors and may redirect such activities to alternative locations.
• Insufficient focal points—it is essential for users to have a clear sense of destination or well-defined pathways leading to points of interest.
• Lack of regular maintenance—insufficient upkeep led to the deterioration of structures and the gradual loss of natural features over time.
• Absence of an intermediate vegetation layer—this lack reduces ecosystem diversity, affecting habitat complexity and biodiversity. It also diminishes the park’s aesthetic appeal and ecological resilience.
• Extensive use of asphalt—even pedestrian-only pathways, including secondary routes, are paved with asphalt, which is visually unappealing, prone to degradation due to roots and frost, and not well-integrated from a landscape perspective.

4.3. Opportunities

Being the core zone of the UNESCO protected area and taking advantage of its layered history and lush vegetation, the park shows valuable potential for hosting the cultural hub of the city of Montecatini and also for offering citizens a liveable place for relaxing. The main opportunities recognized in the area include the following:

• Creation of contemplative and therapeutic spaces—designated areas could offer visitors tranquil environments immersed in the park’s natural beauty, ideal for relaxation, reflection, and rejuvenation. By leveraging the park’s scenic charm to promote mental and emotional well-being, this initiative could attract wellness seekers and nature enthusiasts, reinforcing the park’s reputation as a destination for holistic health and recovery.
• Development of cultural entertainment spaces—this initiative could position the city advantageously in attracting high-quality tourism while serving as a key asset for enhancing other local offerings.

4.4. Threats

Despite the numerous heritage protection constraints, some unsuccessful reuse projects have been started in the past to transform historical thermal structures into modern wellness resorts. This attempt resulted in abandoned construction sites that are particularly detrimental to the park’s appearance and functionality. Beyond being an unresolved issue, this situation highlights the necessity of carefully assessing the feasibility of proposed interventions, particularly in relation to the municipality’s actual resources, with financial constraints being a primary consideration. The threats to be considered are as follows:

• Loss of identity—the integration of modern elements that do not respect the park’s heritage poses a significant risk. The introduction of contemporary features or structures misaligned with the park’s historical and cultural significance could compromise its authenticity and erode its sense of identity.
• Abandoned construction sites—the presence of unfinished or abandoned construction projects can negatively impact the park’s integrity and visitor experience. Such sites not only detract from the park’s aesthetic appeal but also pose safety and environmental hazards.
• Multiple ownerships—fragmented management and the absence of a unified maintenance approach present major challenges. When different parts of the park are owned or managed by separate entities, conflicting priorities, independent decision-making processes, and varying maintenance standards may arise. This lack of coordination can lead to inconsistencies in visitor experiences, uneven resource distribution, and inefficiencies in overall park management. Moreover, the absence of a cohesive governance model can exacerbate issues such as environmental degradation, habitat fragmentation, and infrastructure decay.

The SWOT analysis supported an analytical and detailed understanding of the current condition of Pineta Park and its role in the landscape context. Based on the observations made, it was possible to define preliminary suggestions for the redesign of the area. Figure 6 shows the design recommendations that emerged from the SWOT analysis, highlighting the critical issues and potential of different elements in the park in photographs of the current state.

5. Landscape Strategy

The strategic proposal for Pineta Park is based on the well-being park concept, an innovative approach that redefines urban parks as spaces dedicated to holistic well-being. Designed to address emerging physical, mental, and emotional health needs, the park offers an immersive experience, integrating nature, physical activity, and relaxation. In a post-pandemic world, where self-care has become a priority, the well-being park incorporates sensory pathways, meditation areas, sports facilities, and social spaces, creating a harmonious environment that promotes a healthy and mindful lifestyle. The concept aims to enhance psycho-physical well-being by integrating green spaces, relaxation areas, and regenerative activities. The park is envisioned as an oasis of tranquillity, where contact with nature, physical movement, and meditation become tools for improving quality of life.

In Montecatini Terme, this concept naturally aligns with both the therapeutic vocation of the landscape and the municipality’s intention to broaden the definition of well-being. The park reinforces the historic role of the city as a health-related destination, expanding the range of well-being offerings in line with contemporary trends. Here, the well-being park serves as a modern extension of traditional healing practices, providing visitors with an experience that reflects Montecatini’s identity, blending history, innovation, and nature.

5.1. Design Principles

The guiding principles of our proposal aim to create an environment that is not only aesthetically pleasing but also functional and welcoming for its users, promoting well-being and tranquillity through direct contact with nature. Additionally, the pragmatic constraints of the project have been carefully considered, including the heritage protection regulations and the limited financial resources available to the municipality.

The key principles that serve as guidelines for the proposal are as follows:

• Attractiveness—ensuring that the park remains engaging and appealing year-round by incorporating functions that cater to diverse user groups.
• Variety—designing both open areas with unobstructed views and enclosed spaces suitable for group gatherings or solitude, introducing varied linear pathways to offer diverse spatial experiences.
• Landmark definition—establishing strong focal points that allow clear visibility of destinations and the ability to follow well-defined routes guiding users through the landscape.
• Natural integration—maintaining a balance between natural elements, such as vegetation, and artificial structures, emphasizing the presence of nature while limiting the introduction of new built elements.
• Accessibility—designing barrier-free pathways that ensure universal accessibility and encourage seamless exploration of the park.
• Feasibility—scaling the program in proportion to the technical and financial capacity of the involved stakeholders while considering the impact of the implementation phase on the temporary usability of the park.

These principles were defined based on the design team’s understanding of the broader challenges of spa towns and the specific characteristics of the Montecatini Terme context, developed through the preliminary study and in situ analysis presented in this paper. They informed the design process and served as a reference for the final evaluation phase, as exposed in Section 7.

5.2. Operational Program

The design principles were then translated into an operational strategic program through the identification of various functional areas and a list of activities, as shown in Figure 7. This critical approach aims to enhance the intrinsic qualities of each part of the park while simultaneously reinforcing its overall identity.

Seven functional areas were identified: the Social Park, the Biodiversity Park, the Pinewood, the Sports Park, the Children’s Park, the Botanical Garden, and the Water Museum Garden. The first five areas pertain to the municipal Pineta Park, while the last two correspond to the private parks belonging to the Tamerici and Torretta thermal buildings. These have been included as auxiliary spaces within the regeneration program to preserve and reinforce the unified and systemic structure of the thermal landscape. The strategic proposal for the reuse of the Torretta and Tamerici thermal establishments envisions the creation of a botanical research centre in the former, with the development of a botanical garden within its extensive park, while the latter would be repurposed as a museum of water. The functional areas can be considered as a framework for phased park redevelopment over time. The activities planned for the private areas of Torretta and Tamerici are designed to complement the proposed transformation of the public park, expanding the network of stakeholders involved and strengthening the economic sustainability of the project by incorporating activities that generate economic returns for public administrations.

Within each area, specific activities have been integrated to enhance the park’s potential and key features, while also promoting new and diverse opportunities for use. The proposed design aligns with the objective of strengthening the park’s identity as a space dedicated to well-being and biodiversity, offering various opportunities for physical and mental self-care and fostering the benefits of direct interaction with nature.

5.3. Landscape Program

In addition to the operational program, a landscape program has been defined, focusing on two complementary aspects: hardscape and softscape.

For the hardscape, an analysis of the existing pathway hierarchy was conducted to strategically guide intervention priorities. In particular, two main nodes and two primary axes were identified as key elements for improving circulation within the park and supporting the development of activities in the functional areas. The decision to limit the most invasive interventions within defined and limited areas responds to the need to keep the park accessible and functional during the redevelopment process while also ensuring the optimization of investments in strategically significant locations. The selection of intervention areas aims to maximize the aesthetic, perceptual, and experiential impact through targeted, localized actions.

The softscape analysis, on the other hand, focuses primarily on the water system. In the redevelopment proposal, water is conceived as a key element that connects the historical and contemporary identity of both the park and the city. Water is enhanced as a recreational, sensory, and biodiversity-supporting feature, in synergy with the activities proposed in the operational plan. The main intervention in this regard is the restoration of the Rinfresco stream, aligning with the expansion of the protection perimeter adopted in the 2022 revision of the Structural Plan.

Figure 8 provides a graphical representation of the proposed landscape program. Additionally, Appendix A provides the masterplan summarizing the analysis of the current state and strategy for the area.

6. Landscape Design

Based on the outlined strategy, the proposed intervention includes two categories of actions: structural interventions and auxiliary interventions. The structural interventions focus on the nodes and axes and constitute the core framework of the landscape project, serving as a driving force for any potential future development. These interventions require the greatest economic and technical effort from the municipality, as they aim to establish a strong framework capable of affirming the identity of the thermal district as an interconnected system. In contrast, auxiliary interventions are distributed across the various functional areas and are designed to support the proposed activities and define the character of each area. These interventions do not need to be implemented all at once but can be phased over time based on the municipality’s operational capacity. Together, structural and auxiliary interventions contribute to a unified and integrated vision of the well-being park.

6.1. Structural Interventions

The structural interventions focus on the two nodes and two axes identified in the strategic framework. At a conceptual level, their objective is to create key attractions that reinforce the role of the park within the thermal district and to redefine connections to enhance user experience, making it more engaging and dynamic. At a practical level, the main intervention involves modifying the ground surfaces by removing asphalt and introducing pedestrian-friendly paving and vegetation to visually reinforce the pedestrian-oriented and public character of the space.

6.1.1. Nodes

The two identified nodes are the entrance area in the southern part of the park and the square in the northwestern part. For the entrance (node A), the primary objective is to increase its visibility and recognizability, as shown in Figure 9.

For the square (node B), the goal is to enhance its usability by reducing the parking area and designing an open-air theatre to host civic events (Figure 10). This new multipurpose space can serve as a gathering place for residents and tourists, or function as a performance stage for musical, theatrical, and cultural events. The diverse range of functions and uses proposed for this area also contributes to the financial sustainability of the project, as the space can be rented out for private events.

6.1.2. Axes

The interventions on the axes aim to eliminate the current perception of the boulevard as a vehicular road. Indeed, in addition to asphalt paving, the rigid division created by lateral flowerbeds further reinforces a linear and constrained perception of space. The proposed intervention integrates the redevelopment of these axes into a broader territorial vision for sustainable mobility, incorporating dedicated cycling lanes. Along Viale delle Tamerici (axis a), the bicycle lane has been positioned along the eastern edge of the avenue. The side adjacent to the park has been redesigned to include multifunctional platforms beneath the Tilia cordata trees, encouraging rest and social interaction. Along Via del Rinfresco (axis b), the redesign enhances connectivity between the linear pathway and adjacent park areas, particularly by reshaping the boundary with a curvilinear layout (Figure 11). To accommodate different mobility needs, the cycling lane has been positioned along the northern edge, while pedestrian circulation is oriented toward the park side, where the curved pathway promotes a more dynamic and flexible use of space, creating intermediate resting areas along the route.

The junction between the two axes is further emphasized through the installation of shade umbrellas, providing solar protection for the cycling lane in a section where large trees are absent. Additionally, these urban furniture elements act as a barrier to vehicular access, restricting entry to emergency vehicles only. Figure 12 summarizes the main interventions along the axes.

6.2. Auxiliary Interventions

While structural interventions consist of a limited number of targeted actions aimed at redefining the park’s landscape framework—respecting its historical identity while making the well-being park concept explicit—auxiliary interventions comprise a broad set of smaller interventions distributed throughout the park. The complementarity of and differentiation between structural and auxiliary interventions is a key aspect of the project. The strategy has been carefully designed with full awareness of the municipality’s operational and financial constraints, prioritizing the avoidance of prolonged inaccessibility to large sections of the park. This phased and pragmatic approach is essential to ensure the project’s feasibility, to prevent failures like those experienced in the past, and to preserve the relationship between the citizens and the park. These interventions enhance existing valuable features of the park, such as the watercourse, biodiversity, and opportunities for outdoor sports. Figure 13 shows the set of auxiliary interventions proposed, and Appendix B provides the comprehensive design masterplan and the location of each intervention.

7. Discussion

The design process developed for the Montecatini Terme case study led to a practical design outcome for the landscape enhancement of Pineta Park. As established in the methodology, the final phase of the design process consists of evaluating the outcome in relation to the initially defined design principles and within the theoretical framework of the HUL approach. Although intermediate and partial evaluation phases were integrated throughout the design process—allowing for continuous refinement and improvement of the proposal—this paper presents only the final proposal and discusses the assessment of the final outcome. The strategic and design proposal for Montecatini unfolds across multiple levels: (i) the operational program, strengthening key assets and enhancing intrinsic values; (ii) the landscape program, which integrates the valorization of the natural components with heritage protection and conservation guidelines; and (iii) the design proposal, which translates these strategies into practical interventions, supporting the development of a well-being park and placing it at the core of the landscape system of the thermal city.

The proposed interventions address the needs of different user groups and accommodate diverse requirements. For instance, the inclusion of a playground near the Museum of Water and a water play area along the stream is intended to engage children in nature-based activities, making the park more accessible to families. At the same time, the redesign of the main pathways—incorporating rest areas, seating, and multifunctional platforms—considers the needs of older visitors and individuals with reduced mobility, while also promoting group activities, social interaction, and community cohesion. In addition to gathering spaces and collective activity areas, such as sports facilities, the project includes zones dedicated to tranquillity and introspection, such as the area for forest bathing, a reflexology path, and biodiversity areas with insect houses. In these spaces, the relationship with nature shifts to an individual scale, offering visitors an immersive and personal experience. From the outset, the natural character of the site was identified as its primary asset and key strength. Accordingly, interventions were limited to the main nodes and axes to preserve and expand natural and vegetated areas, while better integrating anthropogenic infrastructure, such as pathways. Finally, feasibility considerations were a guiding factor throughout the design process, leading to a strategic limitation of the most invasive and costly interventions to a few key areas. The resulting program is designed for phased implementation, allowing for step-by-step realization over different time periods. In this way, the design principles established in the initial phase of the design process are respected and fulfilled, as also confirmed by the primary stakeholders involved in the project consultation process, namely, the Municipality of Montecatini Terme and Fondazione Caript. Moreover, the design strategy developed for Montecatini complies with the indicators proposed by Sztubecka, Maciejko, and Skiba for evaluating the environmental perception of spa parks, despite the fact that this study followed a different set of design principles [84]. Furthermore, particular emphasis has been placed on the elements most aligned with the well-being park concept, such as the diverse interactions with nature and its therapeutic function on both a physical and psychological level [22,85].

Regarding the correspondence with the HUL approach, the project proposal supports a dynamic transformation of Pineta Park as the core part of the Montecatini thermal district while respecting its historical identity and also the constraints of heritage protection. Over the past centuries, the topic of heritage conservation has been largely discussed and seen as a necessary action to preserve collective memory and values, even if frequently conflicting with the practical processes and needs of modernity. The design proposal acknowledges the heritage complexity, which “is steeped in legend, rooted in the public’s fascination for past built environments, the representation of history, personal and collective memory values, spirit of place” [85], but also recognizes the urgent issue of the gradual erosion of the physical and social structures that support these values. For these reasons, landscape design and creative approaches are needed to revitalize neglected heritage and to keep alive the tangible and intangible heritage of spa towns, as well as that of other Historic Urban Landscapes. Additionally, new challenges related to climate change, social transformations, and economic and political changes require that heritage also adapt if it is to be preserved and passed on to future generations [86]. In the case of Montecatini, the severe state of neglect and degradation of the thermal facilities, resulting from the crisis of the tourism model centred on hydropinic treatments, necessitates a fundamental rethinking of the thermal city as a system.

In this context, landscape architecture, as an interdisciplinary and multi-scalar discipline, offers design solutions capable of addressing the complexity of these challenges. The landscape-based approach adopted in this study is aligned with the place-based strategy to frame adaptive reuse of thermal heritage proposed by Fabi, Vettori, and Faroldi [38], who stressed the need for a strategic vision and the opportunity for promoting territorial networks centred on spa towns. The redesign of Pineta Park as a well-being park serves as a strategy for revitalizing the city, a tool for reconnecting citizens with their heritage, and a framework for the future reuse of the thermal establishments once their ownership is redefined. The design aspects addressed in the Montecatini project are also relevant to other similar cases of parks in thermal cities. The main challenges faced by the project—such as the need to intervene on primary pathways and implement small-scale revitalization measures—are closely aligned with similar design experiments conducted by Słonina and Skomorowska in various parks of Polish spa towns, as well as with the necessity of ensuring that any intervention remains consistent with the historical character of the site [87]. The research findings are thus consistent with similar studies, particularly those focusing on spa destinations in Central Europe [88]. Notably, the study by Dryglas and Salamaga, which investigated through surveys the added value of therapeutic landscapes in spa destinations, highlighted how the presence of landscape assets in healing environments is particularly significant for visitors choosing these destinations for therapeutic purposes, while also serving as an independent attraction in itself [89]. The scarcity of design references and project experiences related to Western Europe further supports the relevance of this study, as it contributes to expanding the debate and research beyond Central Europe, where thermal tourism continues to play a prominent role.

Last, moving to the main challenges encountered in this design experience, two main aspects must be mentioned. The first challenge was designing an intervention in a context that has been experiencing crisis and decline for decades, where the prevailing sentiment is one of melancholic resignation. The practical difficulty, on the other hand, was primarily tied to budget constraints, ensuring the feasibility of the project. These two aspects are interconnected in the need to develop a well-targeted and balanced proposal, capable of triggering positive dynamics without falling into the trap of making unrealistic promises. In this regard, it is useful to mention both the project cost estimates and the identified funding opportunities. The total estimated cost for the intervention is approximately EUR 3.25 million. However, as previously noted, the modular nature of the interventions is essential for structuring a financial feasibility plan. The structural interventions on nodes and axes require an investment of EUR 2.5 million, while the remaining budget is allocated to auxiliary interventions. Furthermore, the proposed landscape restoration program is well positioned to access multiple funding opportunities, ranging from European to national funds, including those allocated under Tuscany’s National Recovery and Resilience Plan (PNRR) for the promotion of green infrastructure. Thus, the proposal helps the Municipality of Montecatini re-enter a network of regional and supra-regional funding opportunities, reaffirming the significance of its historical, cultural, and landscape heritage.

8. Conclusions

As highlighted in the introduction and in the framing of Montecatini within the Great Spa Towns of Europe, this case study is representative of a broader phenomenon—the crisis of thermal tourism and the decline of traditional spa towns. The complexity of this issue encompasses cultural, political, and economic factors, making it resistant to simplistic solutions. The experience of the Research through Design presented in this paper allowed us to provide a possible answer to the initial research questions.

Regarding the contribution of landscape design to the protection of the heritage of thermal cities, the comparative case study analysis highlighted how the successful revitalization strategies in Bath and Vichy depended on a holistic vision and an understanding of heritage as a landscape system. The design experience in Montecatini confirmed and reinforced this thesis, demonstrating that despite the current state of degradation and the uncertainty surrounding the architectural heritage—due to prolonged abandonment and the impending auction—landscape design remains capable of capturing and effectively expressing the site’s cultural values. Moreover, the project aims to guide the future reuse of architectural heritage, preventing speculative developments through the strong affirmation of the value of high-quality, accessible public space.

As for the second research question, concerning the creation of new values within historical landscapes, the RTD experience yielded significant insights. The reinterpretation of the thermal park as a well-being park illustrates the potential of creative, visionary, and dynamic design approaches. This reinforces the argument that introducing new concepts can generate value when integrated within a coherent landscape project that remains respectful of the historical and cultural identity of the site.

The findings from the design investigation on Montecatini contribute new knowledge to the extensive body of research already conducted on this city. While previous studies have primarily focused on historical aspects and economic–tourism performance, this study introduces an applied research perspective, aiming to integrate multiple dimensions into a landscape design strategy. Moreover, this design experience provides key recommendations for decision-makers, relevant not only to Montecatini but also to other spa towns facing similar challenges. These recommendations can be summarized as follows:

• Recognizing thermal landscapes as a synthesis of cultural values. In the case of Montecatini, the role of Pineta Park as a connector within the thermal system was evident from its original design by the architect Bernardini. However, the therapeutic significance of landscapes is a common theme across many European spa towns and can play a key role in the conservation and enhancement of thermal heritage.
• Using territorial and landscape planning as a tool to prevent the fragmentation of heritage and loss of identity. While this issue is particularly urgent for Montecatini, given the imminent sale of thermal buildings, it is also relevant to other spa towns facing abandonment and degradation. Even in cases where direct interventions on architectural heritage are limited, public authorities can still act on the landscape framework, which is crucial for regulating and guiding potential private investments.
• Investing in environmental and landscape quality to support the architectural and urban conservation of spa towns. Viewing the landscape as an integrated and complex system, investments in environmental quality, green areas, parks, and ecological networks are fundamental to preserving the overall value of the historic urban heritage of spa towns.
• Using landscape design as a unifying theme to engage diverse stakeholders. In Montecatini, for instance, the involvement of Fondazione Caript represents an initial step toward expanding stakeholder participation, with potential for further collaboration in future project phases.
• Leveraging landscape design as a driver for the revitalization of declining thermal contexts. Identifying and enhancing the intrinsic qualities of spa town landscapes and strengthening synergies between cultural and natural elements can act as a catalyst for broader regeneration processes.

Last, the application of the RTD methodology supports and reinforces the recognition of design practice as a tool for investigation and knowledge production. The reflections derived from this RTD experience can be extended to other traditional spa towns facing the consequences of the crisis and decline of their tourism model, as well as the detachment of the city from its identity values. More broadly, the results are relevant to Historic Urban Landscapes in general, particularly where strict conservation constraints have led to heritage crystallization, preventing a dynamic transformation aligned with contemporary needs.
