This work explores issues related to traditional heritage, its evolution, and its transmission within construction practices. It focuses on a case study concerning the reintroduction in Tamentit, an oasis in southwestern Algeria, of a nearly forgotten construction technique: the use of a local stone known as “Agharf”, composed of saline pebbles, bound or assembled with a clay mortar enriched with salt, allowing the construction of robust structures adapted to their environment. Traditionally used in certain specific areas of the Sahara, it was notably employed in isolated regions such as Siwa in Egypt. After a long period of disuse, this technique is experiencing a renewed interest and appears to be gradually reintegrating into the local practices of artisans. This raises several questions: What justifies the return of this technique? What role does contemporary society assign to it, and what actions are being taken to ensure its sustainability? Fieldwork, consisting of on-site observations and semi-structured interviews with artisans and master artisans, the ma‘alem, was conducted to analyze their perception of this heritage, to understand the tangible and intangible aspects of the construction process, and to explore the challenges related to its transmission. The interviews reveal that, despite the challenges and reservations expressed by the community, the Agharf remains for the artisans a symbol of identity and craftsmanship, far from being a lost intangible heritage. The conditions and benefits of its use are also discussed. Full article

Italy is internationally renowned for its cultural heritage, a testament to its rich history. Many of these structures, built before the advent of modern engineering principles, were constructed based on empirical knowledge and lack seismic design considerations, making them highly vulnerable to earthquakes. This vulnerability presents a significant challenge to preserving Italy’s architectural legacy. A notable example is Villa Vannucchi, located in the seismically active Vesuvius region. Given its historical and cultural significance, enhancing its structural resilience while preserving its architectural authenticity is imperative. This study investigates the seismic vulnerability of Villa Vannucchi through a comprehensive analysis of its structural deficiencies and proposes a targeted retrofitting strategy in accordance with the Italian Guidelines for Cultural Heritage (IGCH). The evaluation is conducted in three phases: 1 Preliminary structural assessment—Calculation of two critical safety factors to evaluate the villa’s overall stability. 2 Local collapse mechanism analysis—Examination of the structure’s susceptibility to localized failures. 3 Advanced computational modelling—Detailed simulations revealing critically low seismic coefficients. Based on these findings, a consolidation plan is developed, integrating traditional and minimally invasive techniques. Key interventions include reinforcing the masonry and reducing floor deformability to improve overall structural stability. The implementation of these retrofitting measures significantly enhances the villa’s seismic resilience, as evidenced by the increased safety coefficients. This reduction in vulnerability not only ensures the preservation of Villa Vannucchi, but also safeguards its cultural and historical legacy for future generations. Full article

In this paper, the acoustic characteristics of the most important rooms of the Royal Palace of Caserta are presented. The palace, built in the XVIII century as a residence for the King of Naples, consists of numerous rooms dedicated to court life. The acoustic properties of the rooms have been studied according to ISO 3382. For each room, the average values of reverberation time (T30), clarity (C80), definition (D50), and Speech Transmission Index (STI) are reported. The acoustic issues of the rooms are highlighted as the understanding of acoustics during the period in which the palace was constructed was limited. While the rudiments of Vitruvius’ theories were known, the good acoustics of the rooms resulted primarily from the intuition and experience of the architects who designed them. The building materials—marble and plaster—contribute to the long reverberation times in the rooms. Special attention was given to the elliptical vault where musicians were positioned, the Palatine Chapel, the theatre used for court entertainment, and the Royal Throne Room. The study applies methods and techniques already seen in the literature and already reported in other published papers. Full article

The discovery of an Aurignacian lithic assemblage along the northern coast of the Island of Lemnos in the northeastern Aegean Sea has opened new perspectives on the study of the beginning of the Upper Paleolithic in this region. The site is located some 93 m from the present seashore. It was discovered in the summer of 2020, ca. 2 km west of the Pournias Bay. The lithics were exposed in a well-defined oval concentration, ca. 25 × 10 m wide, buried by a Holocene sand dune. They were uncovered following sand removal by a bulldozer for the construction of a parking lot. The knapped stones are made almost exclusively from hydrothermal siliceous rocks, a raw material available on the island. Raman spectroscopy and optical observations confirmed that this raw material is chalcedony. The surfaces of most artefacts are weathered due to deposition in an environment rich in marine salt, which does not preserve any organic material suitable for radiocarbon dating. The knapped stone assemblage consists of diagnostic artefacts, among which are different types of carinated end scrapers, cores, and a few bladelets. The discovery of an Aurignacian site plays an important role in the study of the Paleolithic peopling of Lemnos and the Northeast Aegean in general, a period that was previously known only through Epipaleolithic sites discovered and excavated mainly along the eastern coast of the island.

A global survey was conducted in 2022 with the aim of identifying what professionals in the cultural and creative industries (CCIs) expect from collection-based organisations (CBOs) and what their contribution to their preservation, management, and/or use could be. A total of 151 responses were obtained from the five UNESCO regions, the majority of whom were between 31 and 50 years of age, which is convenient when analysing the responses as they are active and belong to different creative sectors. The results are very positive, demonstrating that museum collections are didactic materials through which design students and CCI stakeholders learn to approach the past critically and creatively, create meaning, and co-create their future heritage. Likewise, the alliance of CBOs with the SDGs represents a key tool to experiment with and call for action to achieve the goals of the 2030 Agenda. The results enable CCIs to identify and bridge gaps in their role as creative developers, strengthening their collaboration with heritage organisations. This paper aims to show the results of the survey and the first actions aimed at developing meaningful, inclusive arts- and culture-based interventions to support sustainable development.

This study explores the potential of artificial intelligence (AI), specifically ChatGPT, in enhancing the conservation of Algeria’s architectural heritage. By analyzing photographs of historical monuments, the research evaluates ChatGPT’s ability to identify architectural styles, detect pathologies, and propose conservation strategies. The findings reveal that while ChatGPT demonstrates proficiency in recognizing architectural features and generating general descriptions, its accuracy in identifying specific pathologies remains limited, with a certainty rate of only 40%. The tool’s reliance on textual data rather than direct visual analysis, coupled with its inability to meet specific academic requirements such as word count and accurate referencing, underscores its current limitations. However, the study highlights the potential of AI to complement traditional conservation methods, particularly when integrated with comprehensive databases and expert validation. The research advocates for a hybrid approach, combining AI’s efficiency with human expertise, to address the challenges of heritage preservation in Algeria. This work contributes to the growing field of AI applications in cultural heritage, offering insights into both the opportunities and constraints of leveraging AI for sustainable monument conservation.

With the Republic of Türkiye signing the “Convention on Intangible Cultural Heritage” in 2006, awareness and sensitivity towards the safeguarding of cultural heritage has also begun to develop in the Turkish Republic of Northern Cyprus (TRNC), which has close relations with the Republic of Türkiye. However, the intangible cultural heritage convention could not be signed in the TRNC due to political reasons, and this has led to a lack of sufficient change and awareness about it on the island. Regrettably, the limited number of academic studies carried out in universities in this field has proven to be inadequate in terms of creating general public awareness about the subject. However, the knowledge and experience of both the community and individuals working in this field are crucial for the safeguarding and sustainability of cultural heritage elements. In this context, this study collected the knowledge and opinions of personnel affiliated with the TRNC Ministry of Culture on the subject of intangible cultural heritage (ICH), and it investigated whether the adequacy of the personnel’s knowledge and opinions around cultural heritage had a direct impact on its safeguarding and sustainability. This research used a type of mixed method called “Convergent Mixed-Methods Design”. The sample of this research consisted of 30 personnel working in different units affiliated with the Ministry of Culture in Northern Cyprus. This study included personnel working in different units and positions affiliated with the ministry. An interview form was used to obtain the data that formed the basis of this research. The interview form consisted of 10 structured and 3 semi-structured questions prepared by the researchers. Descriptive statistics were used in the analysis of the quantitative data, and content analysis was used in the analysis of the qualitative data. This study, which aimed to determine the knowledge and opinions of Ministry of Culture officials working in the TRNC regarding the safeguarding and transfer of intangible cultural heritage elements, revealed that the employees were not fully informed about the scope, objectives, and protection of ICH.

This study investigates the deterioration of granite graffiti at the Philae Archaeological Site on Bigeh Island (Aswan, Egypt), attributed to Khaemwaset (1281–1225 BCE, 19th Dynasty). These graffiti, despite being carved into durable Aswan granite, are experiencing progressive degradation due to environmental and hydrological factors. This research aims to analyze the mineralogical and chemical transformations affecting the graffiti to provide a comparative assessment of submerged and unsubmerged granite surfaces. A multi-analytical approach was employed, combining petrographical examination, X-ray diffraction (XRD), X-ray fluorescence (XRF), and scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS) to identify compositional changes and deterioration patterns. The results indicate mineralogical transformations in submerged and periodically exposed surfaces. The granite primarily consists of quartz, feldspar, and biotite, with notable alterations including kaolinization and illitization and dissolution of feldspar minerals and biotite oxidation. These processes are directly linked to prolonged exposure to fluctuating water levels and recurrent wet–dry cycles, which accelerate granular disintegration, exfoliation, and surface loss. Additionally, salt crystallization, particularly halite, contributes to granite weathering, while sulfate interactions promote chemical weathering. In addition, biofilm colonization, facilitated by high moisture retention, further exacerbates surface deterioration by producing organic acids that weaken the mineral matrix. Finally, the results confirm the need for conservation interventions to mitigate ongoing damage. Full article

Paint loss is one of the major forms of deterioration in ancient murals and color paintings, and its detection and segmentation are critical for subsequent restoration efforts. However, existing methods still suffer from issues such as incomplete segmentation, patch noise, and missed detections during paint loss extraction, limiting the automation of paint loss detection and restoration. To tackle these challenges, this paper proposes PLDS-YOLO, an improved model based on YOLOv8s-seg, specifically designed for the detection and segmentation of paint loss in ancient murals and color paintings. First, the PA-FPN network is optimized by integrating residual connections to enhance the fusion of shallow high-resolution features with deep semantic features, thereby improving the accuracy of edge extraction in deteriorated areas. Second, a dual-backbone network combining CSPDarkNet and ShuffleNet V2 is introduced to improve multi-scale feature extraction and enhance the discrimination of deteriorated areas. Third, SPD-Conv replaces traditional pooling layers, utilizing space-to-depth transformation to improve the model’s ability to perceive deteriorated areas of varying sizes. Experimental results on a self-constructed dataset demonstrate that PLDS-YOLO achieves a segmentation accuracy of 86.2%, outperforming existing methods in segmentation completeness, multi-scale deterioration detection, and small target recognition. Moreover, the model maintains a favorable balance between computational complexity and inference speed, providing reliable technical support for intelligent paint loss monitoring and digital restoration.

This study explores the application of Eastern philosophy in craft innovation education, identifying opportunities for interdisciplinary learning. Drawing on the I Ching and Laozi’s thought, it examines human needs in craft across three dimensions: Qi-form (material), Xin-form (psychological), and Dao-form (philosophical). Taiji theory’s Yin–Yang balance highlights the importance of interdisciplinary thinking in craft innovation. This study introduces the “Spiral Innovation Theory” as a framework for craft education, implemented in the 2024 Taiwan Craft Academy Summer Program with 43 participants. The curriculum covered lacquer, wood, metal, and ceramics, employing a multi-mentor system. Using the Learning Motivation Strategies Scale, Imaginative Thinking Scale, and interviews, the findings reveal that different crafts foster distinct creative abilities. The ANOVA results show woodworking enhances ideation, metalwork and ceramics improve fluency, ceramics and woodworking strengthen flexibility, while woodworking and lacquer work boost creativity. A significant correlation between learning motivation and imagination was found. These findings offer insights into future craft education, advocating the dual mentorship model as a strategy for interdisciplinary innovation. Full article

Cultural heritage preservation and dissemination face significant challenges in the digital era, particularly in artifact representation, visitor experience personalization, and virtual exploration scalability. This paper presents a tool for the development of a virtual museum, introducing a new system that addresses the challenges of the design and arrangement of the virtual environment process with two integrated stages: (1) Museum Generator, a procedural tool for creating realistic and adaptable virtual museum environments and (2) Artwork Arrangement, an automated system that optimizes the placement of artifacts based on thematic and spatial considerations. The system is validated through a Grid Search Method experiment that seeks to identify the combination of genetic operators that maximizes performance in arranging artworks in a virtual museum and evaluate how modifications to these operators affect the performance of different evolutionary executions. Results indicate that the proposed approach provides an effective and scalable solution for contributing to the design and arrangement of a virtual environment for museums, fostering greater accessibility to cultural heritage and delivering personalized visitor experiences.

Artistic masterpieces are mostly collected in museums located in the center of urban areas, which are prone to heavy traffic. Traffic-induced vibrations can represent a significant hazard for museum objects, due to the repeated nature of the excitation and the brittle, pre-damaged condition of the artifacts. This is the case of the Sarcophagus of the Spouses, displayed at the National Etruscan Museum of Villa Giulia in Rome. Vibrations on the floor of the room are measured by means of velocimeters, highlighting substantial vertical amplitudes and recommending the design of an isolation system. For its design, the dynamic identification of the statue is essential, but the use of contact or laser sensors is ruled out. Therefore, a recent technique that magnifies the micromovements present in digital videos is used and the procedure is validated with respect to constructions where the dynamic identification was available in the literature. In the case of the Sarcophagus, identified frequencies are satisfactorily compared with those of a finite element model. The recognition of the dynamic characteristics shows the method’s potential while using inexpensive devices. Because costs for cultural heritage protection are usually very high, this simple and contactless dynamic identification technique represents an important step forward. Full article

This review explains why pore structure characterisation, particularly utilising gas sorption and mercury porosimetry, is important for the study of many different types of heritage materials, such as for determining their raw materials, methods of fabrication, and ancient uses. It then describes the basic experimental methods, including details of particular relevance to heritage materials. Several relatively novel methods, such as gas over-condensation, scanning curves and loops, and hybrid experiments, not often used with heritage materials, are also described and their potential applications discussed. In particular, gas over-condensation can probe pores of sizes from the molecular scale to hundreds of microns in one experiment, and thus can be used to provide “fingerprints” characteristic of the internal void space of different types of ceramics or glasses to aid in identification without damaging the finds. This work also surveys the various applications of gas sorption and mercury porosimetry to ancient ceramics, glasses, and building materials, with particular discussion of uses in testing the mode of action and effectiveness of various conservation methods.

As the global population ages, more older adults are engaging with the historic environment than ever before. However, the needs of this population may not always be met by local and national heritage sites and organizations. Here, eight professionals working in the UK heritage, health and well-being and aging sectors were interviewed to gather their views on how older adults interact with the historic environment. Three key themes emerged from these interviews: barriers to accessing the historic environment; positive well-being implications of engaging with the historic environment; and the need to develop a wider knowledge base. Barriers to accessing the historic environment include physiological barriers, such as mobility issues, psychological barriers, and financial barriers. Positive well-being derived from engaging with the historic environment are explored in two key themes: communal well-being, and personal well-being. Attention is drawn to activities developed by heritage organizations to engage with older adults, and how these can be better coordinated and implemented to maximize the benefits the historic environment can offer, and minimize the barriers.

This paper examines multisensory museums, envisioned as extended or hybrid realities where the physical and digital coexist to offer cognitively and emotionally engaging experiences to the public, while enhancing the sense of authenticity. Multisensory communication can improve accessibility, as it conveys the content through multiple perceptual channels, and it can solicit more inclusive, participatory, and creative audience engagement through the stimulation of emotions. A methodological approach to digitisation, communication strategies, interaction, creative storytelling, immersive technologies, and accessibility issues are discussed in depth, in relation to emerging museological practices. Machine learning and generative AI are opening new scenarios in management practices and decision-making, in data analyses and in natural language processing, and in the creation of personalised content addressed to the audience. A short overview about how these algorithms evolve and work is presented, considering the challenges, threats, expectations, and ethical implications they pose. Another key topic is the sense of authenticity. How is it changing in today’s users? How do virtual and mixed realities, storytelling, and user experience design in museums influence it? This paper explores these issues, presenting some case studies which have cultural, social, philosophical, and ethical implications, at a time when museums are redesigning their role in a society undergoing profound transformation.

In the digital 3D reconstruction of the shapes and surface reflectance of ancient paintings and drawings using Photometric Stereo (PS) techniques, normal integration is a key step. However, difficulties in locating light sources, non-Lambertian surfaces, and shadows make the results of this step inaccurate for such artworks. This paper presents a solution for PS to overcome this problem based on some enhancement of the normal integration process and the accurate measurement of Points of Interest (PoIs). The mutual positions of the LED lights, the camera sensor, and the acquisition plane in two custom-designed stands, are measured in laboratory as a system calibration of the 3D acquisition workflow. After an introduction to the requirements and critical issues arising from the practical application of PS techniques to artworks, and a description of the newly developed PS solution, the measurement process is explained in detail. Finally, results are presented showing how the normal maps and 3D meshes generated using the measured PoIs’ positions, and further minimized using image processing techniques, which significantly limits outliers and improves the visual fidelity of digitized artworks.

Louise Nevelson’s Erol Beker Chapel of the Good Shepherd (1977) is a sculptural environment consisting of wooden sculptures painted a monochromatic white color. The paints show signs of degradation including cracking, chipping, peeling, and the formation of blisters and powdery efflorescence. A significant amount of pentaerythritol (PER) detected during a former analysis was concluded to originate from an alkyd paint. We show that the PER originates from the PVAc paint on the sculptures, which we have determined to be an intumescent, fire-retardant (IFR) coating. IFR paints and coatings are functional materials designed specifically to delay the combustion of their substrate. At least one other sculpture by Louise Nevelson is known to have been painted with an IFR coating. Our analyses by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), pyrolysis–gas chromatography/mass spectrometry (Py-GCMS), and cross-section microscopy show the presence and distribution of common IFR additives including PER, dicyandiamide, melamine, inositol, ethylenediamine, and phosphates. These are present throughout the PVAc paint and are enriched in the powdery efflorescence. In addition, the degradation behavior of the paint is typical for IFR coating systems that have been exposed to uncontrolled environmental conditions and especially high humidity events.

The management of museums and cultural heritage institutions requires a collaborative approach that involves diverse actors in decision-making. This study analyses four models of cultural management (dependent, autonomous, non-profit, and private) through case studies on the island of Gran Canaria, highlighting their advantages and limitations. As a result, a hybrid model of governance is proposed that integrates elements of the public, private, and social sectors, promoting the active participation of all stakeholders. However, the implementation of this model faces challenges such as resistance to change on the part of some institutions, the difficulty of coordinating divergent interests between public and private actors, and the need to establish regulatory frameworks that facilitate collaboration without compromising heritage conservation. Despite these obstacles, this approach seeks to improve the sustainability, efficiency, and adaptability of heritage institutions to contemporary tourism and conservation challenges. Full article

This article explores the methodological framework and examines the learning and scientific outcomes of a workshop activity centred on the innovative integration of digital heritage approaches with design thinking methodologies. The workshop was developed in the Italian central Apennines and it investigated the design implications of working on heritage contexts in marginal areas using innovative digital tools, as well as the impact of this approach on the community. The activities engaged international students and professors, employed a multidisciplinary, transdisciplinary, and trans-scalar approach encompassing field research, data processing, dialogue, and collaborative visioning. The findings are both methodological and thematic. Methodologically, the workshop introduced a novel approach to architectural education by integrating digitalization in the design process and by fostering an urban vision that bridges research with local needs. Thematically, the outputs explore new uses for “potential spaces”, sustainable mobility, heritage-led strategies, and tourism, emphasizing community involvement. The workshop’s originality lies in its cognitive, narrative, and design processes, where digital data are part of the creative process. Despite the workshop’s compressed timeline, it successfully fostered creative thinking and practical solutions, demonstrating the value of intense, interdisciplinary collaborative visioning for heritage regeneration. The workshop’s broader implications include potential spin-offs into future community engagement and knowledge-transfer activities, highlighting its social and practical relevance. Full article

This paper examines the growth of climate change discussions in narratives concerning the development and evolution of human societies in Ancient China over the past two decades. This shift reflects climate’s ascension from a marginal factor to a central player in reconstructions of past human actions and societies. We provide an overview of the expanding research on ancient human–climate interactions in China’s prehistory and early history, emphasizing the increasing importance attached to climate as a major player in the rise and, significantly, the collapse of these societies. Through a meta-analysis of publication trends in the last two decades, we identify the chronological periods and topics where climate has come to be interpreted as having a notable impact.

Climate change increases the importance of maintaining environmental conditions suitable for preventive conservation within museums. The microclimates at the Natural History Museum of Vienna, a large national collection housed within a classical building, were studied using >200 data loggers placed from mid 2021 to provide thermo-hygrometric measurements at 15 min intervals. Daily mean temperatures showed exhibition halls typically had the warmest rooms. This was due to the heating in winter and open windows on summer days. The halls can become even hotter than the outside temperature. In winter, most areas of the museum were very dry, as heating lowered the relative humidity, typically to 25–35% for the coldest season. Opening hours imposed daily and weekly cycles on the internal climate. There was little difference between sunny and shaded parts of the building or adjacent offices, corridors and depots. Similarly, the microclimate at the floor resembled that of the room air some ~2 m above. Mechanically controlled microclimates in cold storage areas maintained 10 °C and relative humidity ~50%, but this had become increasingly difficult in hot summers. While there was little apparent damage to the collection, at times, the museum had an extreme indoor climate: very hot in the summer and dry in the winter. Full article

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.

Mycenaean glass artifacts, such as beads and relief plaques, are highly susceptible to degradation, which can significantly modify their visual attributes and pose classification challenges. Corrosion on glass and faience artifacts has often led to misinterpretation, since the visual manifestations of degradation can be similar for both materials, impacting research conclusions. This paper presents a segment of a broader study conducted within the Myc-MVP project, utilizing advanced scientific methods to analyze the compositional changes in corroded vitreous artifacts. Through Macro-X-ray Fluorescence (MA-XRF) and LED microscopy, we aim to understand the correlation between compositional alterations and visual degradation manifestations. The use of MA- XRF was particularly crucial for non-destructively mapping the elemental distribution over large surfaces, allowing for a more comprehensive analysis of corrosion patterns. The results presented in this study are from a subset of artifacts examined using MA- XRF, highlighting critical insights into the spatial compositional shifts that contribute to visible deterioration. This paper discusses the first real-life contribution of Macro X-ray Fluorescence (MA-XRF) imaging to mapping the spatial compositional changes that occur when Mycenaean vitreous materials undergo degradation, yielding visible deterioration. MA-XRF scanning offers a fully non-invasive and non-destructive method for recording compositional data across the entire surface of an object. The results can be visualized as distribution images, which are more accessible and interpretable for a broader audience compared to the spectra generated by traditional spectrometric techniques. These findings aspire to inform strategies for the accurate classification, effective management, appropriate conservation treatment, and long-term preservation of vitreous artifacts. Full article

This paper examines the regional diversity in Buddhist heritage and its use for tourism in Asia, more specifically, South Asia and Southeast Asia. Based on an analysis of secondary sources and data from national tourism organisations, it illustrates inter-regional and intra-regional aspects of tourism related to Buddhist heritage. It is found that in spite of their archaeological nature, Buddhist sites in South Asia are converging points for Buddhist tourism, as these are directly related to the Buddha, and many international Buddhist monasteries enliven them with transnational Buddhist practice. Whereas in Southeast Asia, Buddhism is more of a cultural landscape that pervades from the village-level practice of Buddhism to monumental places dedicated to Buddha, which collectively form a major resource for cultural tourism. This paper argues that regional connections and religious and cultural similarities of Buddhist heritage in countries of Southeast Asia contribute to the cultural distinctiveness in the Asian paradigm that can foster sustainable development of tourism in the region.

The main purpose of the review is to analyze the terminology and methodologies for conservation treatment in cultural heritage conservation, in particular, to define key terminology (such as quality, compatibility, efficacy, and durability); to identify methodologies for assessing conservation interventions; to examine case studies where these assessment techniques have been applied. A summary of the various definitions of terms such as quality, compatibility, efficacy and durability found in the literature is provided. This is followed by a presentation of some theoretical approaches found in the literature on how to evaluate different aspects of conservation interventions. Some more practical examples are then considered, with a focus on mural paintings. Finally, the importance of monitoring interventions over time in the context of preventive conservation is highlighted. The present review emphasizes that key concepts such as compatibility, efficacy, and durability are inherently flexible and context-dependent, often overlapping and evolving according to cultural heritage typology, intervention methods, and environmental conditions.

This pioneering study examines metallographic characteristics of 19th-century steel semi-finished products, kept by the National Museum of Slovenia. These artefacts, manufactured in pre-industrial ironworks in present-day Slovenia, reflect the craftsmanship and technological practices of their time. Metallographic analyses revealed significant microstructural variations within individual samples, attributed to differences in carbon content, cooling rates, and forging techniques. All samples contain non-metallic inclusions composed of Si, Mn, and other oxide-forming elements. The results indicate that the semi-finished products were often manufactured by combining steels with varying carbon contents and were sometimes hardened. Additionally, this study highlights correlations between the metallurgical properties of the analysed materials and their historical classification as “iron” or “steel”. Full article

The development of advanced diagnostics tools for investigating artworks and monitoring their health state in a non-destructive way is a key point for their preservation and restoration. Non-invasive diagnostic approaches enable the identification of damage often hidden to restorers’ naked eyes, thereby facilitating the planning of appropriate restoration interventions. Here, the combined use of three full-field imaging techniques: shearography, thermography, and structured-light 3D scanning, has been employed as complementary tools for the diagnostics of a panel painting. As a case study, the artwork Consegna della regola Francescana, created by the Neapolitan painter Colantonio around 1445, was analyzed. The integrated application of the mentioned optical imaging techniques allows a comprehensive evaluation of the state of conservation of the work, revealing inserts, nails, and detachments. This synergistic approach also enhanced the interpretation of the results from each individual technique, offering a more complete understanding that would be unattainable with any single method alone.

This paper explores the complex landscape associated with the evaluation of the impact of digital cultural heritage initiatives within the European Union. While the present body of research has so far addressed various facets of digital culture and heritage, including digital humanities, a comprehensive understanding of the impact of digital heritage (i.e., LAM) projects on broader cultural, social, and economic contexts remains a critical gap. This is particularly important given the increasing emphasis on demonstrating value of and securing support for these initiatives. The EU recognizes this strategic importance, promoting digital transformation within the cultural heritage sector and setting ambitious digitization goals. However, the shift from digitization to digital transformation, alongside the more traditional concerns of access and preservation, requires a focus on sustainability, encompassing social and environmental impact, long-term preservation, and economic viability. By employing critical desk research, this paper examines the EU policies concerning digital cultural heritage and the challenges of measuring impact, discussing key concepts like sustainability and digital maturity. It provides an overview of prominent impact assessment frameworks, analysing their strengths and limitations and considering their appropriateness for today policy context. We conclude by arguing the importance of developing and applying holistic IA frameworks that consider the diverse values and long-term sustainability of digital cultural heritage initiatives, facilitating a shift from simply collecting data to demonstrating meaningful change.

The concept of value seems to have capital importance both in the scientific literature and in various heritage actors’ professional discourse. The actions undertaken to develop the built environment inherited from previous generations seem to depend on the value we assign it. In this essay, the concepts of value, assessor, and heritage assessment are discussed. Two historical contexts are compared: the classical axiology of the 19th century based on the Enlightenment search for rationality and the typologies of contemporary values struggling with complexity. This historical reassessment shows a complexification and multiplication of evaluation grids, as well as the need to question the subjectivity inherent in heritage actors’ decisions. In order to not sink into excessive relativism definitively discrediting any attempt to make the process of heritage assessments more objective, a dynamic point of view is proposed, linking the constructivist approach with the use of a criteria-based value grid.

The paper explores the significance of digitalization and spatial modeling for the preservation and management of cultural heritage, addressing challenges posed by architectural complexity and extensive data volumes and developing a tailored data model to organize and integrate geometric, material, and historical information. The case study of Pitti Palace in Florence, Italy, is proposed, considering that its architectural complexity and cultural significance require innovative approaches to documentation and management. The “Pitti Data Model” is proposed as a tailored information system to organize and manage the data. It classifies spaces by adopting a hierarchical approach that supports detailed spatial analysis and reflects the historical and functional diversity of the site. The model links geometric data with thematic data such as material types, state of conservation, and historical names of spaces, providing a multi-dimensional understanding of the building. Based on Getty’s Art & Architecture Thesaurus (AAT), a controlled vocabulary was employed to ensure semantic consistency and interoperability. This semantic enrichment facilitates the integration of geometric data with broader heritage information systems. The paper presents, therefore, the integration in existing standards like INSPIRE, CityGML, and IndoorGML, thus providing a data model supporting efficient querying and visualization in a GeoDB that integrates spatial and non-spatial data, supporting collaborative and sustainable heritage management by enabling advanced analyses such as visitor flow optimization and conservation planning. This aligns with the concept of Heritage Digital Twins (HDT), which are interactive, evolving representations of cultural assets. HDTs support collaborative and sustainable heritage management by enabling stakeholders to access, analyze, and update information in real time. Full article
