Hydrogels, characterized by their high water content, tunable mechanical properties, and excellent biocompatibility, have emerged as a promising material platform for the preservation of cultural heritage. Their unique physicochemical features enable non-invasive and adaptable solutions for environmental regulation, structural stabilization, and antifungal protection. This review provides a comprehensive overview of recent progress in hydrogel-based strategies specifically developed for the conservation of cultural relics, with a particular focus on antifungal performance—an essential factor in preventing biodeterioration. Current hydrogel systems, composed of natural or synthetic polymer networks integrated with antifungal agents, demonstrate the ability to suppress fungal growth, regulate humidity, alleviate mechanical stress, and ensure minimal damage to artifacts during application. This review also highlights future research directions, such as the application prospects of novel materials, including stimuli-responsive hydrogels and self-dissolving hydrogels. As an early exploration of the use of hydrogels in antifungal protection and broader cultural heritage conservation, this work is expected to promote the wider application of this emerging technology, contributing to the effective preservation and long-term transmission of cultural heritage worldwide.

As the cradle of Jiangnan culture, Suzhou is home to a dense concentration of historical architectural heritage that is currently facing existential threats from rapid urbanization. This study aims to develop a spatial heritage corridor network for conservation and sustainable utilization. Using kernel density estimation, this study identifies 15 kernel density groups, along with the Analytic Hierarchy Process (AHP), to pinpoint clusters of historical architectural heritage and assess the involved resistance factors. Current Effective Conductance (CEC) theory is further applied to model spatial flow relationships among heritage nodes, leading to the delineation of 27 heritage corridors and revealing a spatial structure characterized by one primary core, one secondary core, and multiple peripheral zones. Based on 15 source points, six cultural relics-themed routes are proposed—three land-based and three waterfront routes—connecting historical sites, towns, and ecological areas. The study further recommends a resource management strategy centered on departmental collaboration, digital integration, and community co-governance. By integrating historical architectural types, settlement forms, and ecological patterns, the research builds a multi-scale narrative and experience system that addresses fragmentation while improving coordination and sustainability. This framework delivers practical advice on heritage conservation and cultural tourism development in Suzhou and the broader Jiangnan region. Full article

The removal of iron deposits on shipwreck surfaces by mechanical cleaning is labour-intensive work. This study develops an in situ gel and peeling cleaning method, utilising a carboxymethyl chitosan/tannic acid (CMCS/TA) colloidal solution spray on the surface of ferruginous deposits, promoting their removal by adhesion, chelation, and electrostatic bonding processes. The investigation confirmed that the CMTA-2 sample exhibited a sprayable viscosity of 263 mPa/s, the largest single removal thickness of 1.01 mm, a significant reduction in the fe/s atomic ratio by 2.53 units, and enhanced the deposit removal homogeneity. The field testing of the Nanhai I cultural relic showed a 14.37% reduction in iron concentration and a significant decrease in red colour (Δa* = 4.36). The synergistic mechanism involves TA chelating Fe²⁺/Fe³⁺ ions, while the CMCS gel network facilitates interfacial adhesion and mechanical peeling, hence promoting efficient and controllable cleaning.

Early modern theologians often cast female curiosity as both a moral flaw and an epistemic transgression. Aware of this suspicion, Teresa of Ávila professed to have renounced such dangerous impulses in her youth. Yet the persistent presence of curiosity in her writings suggests a strategic redeployment—one that fosters attentiveness and subtly renegotiates ecclesiastical authority as she actively advances reform within the Carmelite order. Through life-writing and scriptural exegesis, Teresa cultivates a disciplined appetite for knowledge: an appetite that outwardly conforms to, yet quietly subverts, doctrinal anxieties surrounding women’s intellectual desires. Her use of curiosidad moves fluidly between sacred and secular registers—sometimes connoting superficial fascination, at other times signaling a deeper, interior restlessness. Resisting reductive interpretation, Teresa reveals a sophisticated and self-aware engagement with a disposition both morally ambiguous and intellectually generative. The same culture that once feared her intellect would ultimately aestheticize it. After her death, Teresa’s relics were fragmented and displayed in Philip II’s Wunderkammer, transforming her once-condemned curiosidad into curiositas, an imperial collectible. Reading Teresa alongside her posthumous interpreters—Fray Luis de León and Miguel de Cervantes—this essay explores how her radical epistemological ambition reverberated through Spanish intellectual culture. Spanning this cultural arc—from sin to spectacle, from forbidden desire to sanctified display—Teresa emerges as a masterful theorist and activist reformer of spiritual authority. In these expansive roles, she reveals the immense and often contradictory power that curiosity wielded in the early modern world. Full article

Epoxy resins have been extensively employed in cultural heritage conservation as both adhesive and reinforcement materials owing to their exceptional bonding strength, relatively low toxicity, and cost-effectiveness. This review initially outlines the fundamental material characteristics of epoxy resins and subsequently examines their contemporary applications in artifact restoration. Subsequently, it synthesizes the research advancements documented over the past two decades, with a focus on critical challenges associated with their application in cultural heritage preservation, including susceptibility to aging, inherent brittleness, and prolonged curing time. The corresponding modification strategies are systematically examined, including strategies for aging resistance enhancement, toughness improvement, and rapid-curing techniques. Finally, potential future directions for epoxy resin applications in conservation are critically evaluated. This review provides a comprehensive analysis of epoxy resins’ performance and modification methodologies, thereby offering valuable insights to guide future research on its application in cultural heritage conservation.

The Huangshan site in Nanyang, situated at the junction of the Nanyang Basin and the Jianghan Plain, represents a critical region for understanding the northward expansion of rice farming in China. Due to the scarcity of suitable organic material, the dating of the channel section at Huangshan relies primarily on cultural relics. By employing grain-size analysis, pollen analysis, and phytolith analysis on sediment samples from the site’s river section, we established a comprehensive framework of hydrology, climate, vegetation, and agricultural activities during the Yangshao to Qujialing periods (ca. 7000–4600 BP). The findings indicate a relative decline in temperature during the Yangshao period, followed by a return to warm and humid conditions during the Qujialing period, which coincided with the peak intensity of rice farming. The continuous expansion of rice farming at the Huangshan site during prehistoric times is likely linked to the northward spread of Qujialing culture. The large-scale production of rice not only provided an economic foundation for the growth of the Huangshan settlement but also facilitated its development into a regional hub for jade production and trade. This study offers new environmental archaeological insights into the interactions between the middle Yangtze River region and the Central Plains during the late Neolithic period. Full article

Traditional villages (TVs) and intangible cultural heritage (ICH) serve as dual carriers for the living transmission of agrarian civilization, with their spatial compatibility being crucial for the sustainable development of cultural ecosystems. Existing research shows deficiencies in quantitative analysis, multidimensional driving mechanism interpretation, and spatial heterogeneity identification. This study establishes a three-phase framework (“spatial pattern identification–spatial relationship analysis–impact mechanism assessment”) using nationwide data encompassing 8155 TVs and 3587 ICH elements. Through the comprehensive application of the spatial mismatch index, Optimal-Parameter Geographic Detector (OPGD), and multiscale geographically weighted regression (MGWR) model, we systematically reveal their spatial differentiation patterns and driving mechanisms. Key findings: First, TVs exhibit a “three-primary-core and two-secondary-core” strong agglomeration pattern, while ICH shows multi-center balanced distribution. Significant positive spatial correlation coexists with prevalent mismatch: 65% of China’s territory displays positive mismatch (ICH dominance) and 35% displays negative mismatch (TV dominance). Second, the spatial mismatch mechanism follows a “weakened natural foundation with dual drivers of socio-economic dynamics and cultural policy momentum”, where the GDP, tertiary industry ratio, general public budget expenditure, number of ICH inheritors, museums, and key cultural relic protection units emerge as dominant factors. Third, core drivers demonstrate significant spatial heterogeneity, with economic factors showing differentiated regulation while cultural policy elements exhibit distinct regional dependency. The proposed “economy–culture” dual governance approach, featuring cross-scale analysis methods and three-dimensional indicator system innovation, holds practical value for optimizing cultural heritage spatial governance paradigms.

The protective materials for cultural relic buildings generally have a deficiency of relatively shallow penetration depth. Based on the principle of changing the permeability coefficient of cultural relic buildings by “water blocking water” and considering the characteristics of magnesium acrylate polymer and the requirement of extending the curing time, a method of modifying magnesium acrylate polymer with glycerol and sodium methyl silicate is proposed. Experimental studies on magnesium acrylate, glycerol–magnesium acrylate, and sodium methyl silicate—glycerol–magnesium acrylate polymers were carried out, and tests and analyses on curing time, swelling performance, water loss rate, and soil sample protection were conducted. The results show that the initiator concentration is a key factor affecting the curing rate of magnesium acrylate polymers. When the initiator content is ≥4%, the curing time is significantly shortened to 20–67 min, and the incorporation of glycerol prolongs the curing time by more than 100 min through the dilution reaction system. Glycerol modification significantly enhanced the swelling capacity of the polymer, with the swelling rate increasing by approximately 15–20% compared to the unmodified system. Sodium methyl silicate effectively improved the construction performance of magnesium acrylate and prevented the occurrence of bubbles. The optimal formula of magnesium acrylate polymer is 25% magnesium acrylate, 40% glycerol, and 2% sodium methyl silicate. While maintaining curing for 120 min, it features a high swelling rate (equilibrium swelling ratio Ew ≈ 0.32) and a low dehydration rate (dehydration rate ≤ 35% after 48 h), and has volume stability after interaction with soil samples.

As a core structure within the Qing Changling Mausoleum, a UNESCO World Cultural Heritage site, Long’en Hall preserves a relatively complete set of Qing dynasty imperial lacquered furniture. These furnishings provide critical physical evidence for studying Qing dynasty sacrificial rituals and the craftsmanship of court lacquerware. However, limited research has been conducted on the surface finishing techniques of such furnishings, posing challenges to their conservation and accurate restoration. This study focuses on representative furnishings from Long’en Hall—including an offering table, an incense pavilion, a throne, and a poke lamp—and employed a multi-method analytical approach comprising fluorescence microscopy (FM), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared (FTIR) spectroscopy. The analysis was conducted on the following two levels: the lacquer layer structure and material composition. The results show that the furnishings in the Long’en Hall adopt the typical structure of “lacquer ash layer–color lacquer layer”, and the color lacquer layer is composed of raw lacquer, tung oil, animal glue, and other natural organic ingredients as film-forming materials, supplemented with inorganic mineral pigments such as red lead (Pb₃O₄) and Au metal, which constitutes a stable organic–inorganic composite structure with the lacquer ash layer. The multi-analysis results show a good complementary and cross-corroboration relationship, providing the necessary technical support and a theoretical reference for Qing dynasty palace lacquer wood furniture as cultural relics worthy of scientific protection and imitation.

The rural landscape serves as a window to showcase regional culture and can drive the development of the rural cultural tourism industry. However, driven by the rural revitalization strategy, the construction of rural landscapes in the Yangtze River Delta region faces the challenges of homogeneity and lack of authenticity. A regional evaluation of the rural landscape and strategic suggestions are key to solving this problem. Therefore, this study selected three representative villages in the Yangtze River Delta region and established a regional evaluation model of the rural landscape in the Yangtze River Delta from the perspective of the ecological–production–living concept, utilizing the analytic hierarchy process, a tourist questionnaire survey, IPA, and Munsell color analysis. The results show that (1) the core indicator of the rural landscape regionality is the life landscape, followed by the production landscape, and finally, the ecological landscape; (2) the overall satisfaction of the rural landscape is high, and the satisfaction of the water network landscape is significantly higher than other indicators; (3) the results of IPA show that what needs to be maintained are traditional dwellings and historical relics, and what needs to be improved are sign design and rural public art design; (4) Munsell color analysis shows that the characteristics the of rural landscape in the Yangtze River Delta region are diverse and inclusive. This study is of great significance for maintaining the characteristics of the rural landscape in the Yangtze River Delta region and promoting the protection of rural landscape style under different regional conditions.

Internationally, there is a modern understanding of cultural heritage, including maritime/underwater cultural heritage (MUCH)—not merely as a passive relic of the past, but as a transformative driver for sustainable growth and innovation. The paper discusses the position of maritime cultural heritage (MUCH) in relation to the smart specialization strategies (S3) and its evolving role as a driver of sustainable growth, particularly within the context of the blue economy and smart specialization strategies (S3, S4) in Europe. It then focuses on the Greek context, where UCH-driven activities, particularly soft multi-use (MU) activities that combine UCH, diving tourism, and nature conservation, are gaining momentum, especially within marine protected areas (MPAs). Despite the growing interest, there is a lack of data, regulations, and a clear strategy for such activities, although the “National (Hellenic) Spatial Strategy for the Marine Space” (issued in 2025) suggests promoting low-impact diving tourism incorporating UCH. The research paper examines the benefits and barriers to implementing UCH-driven MUs, recommending the use of maritime spatial planning (MSP) to address relevant challenges. It suggests that integrating UCH with nature conservation and diving tourism in soft MUs could support a sustainable blue economy, through balancing cultural, ecological, social, and economic goals and fostering innovation through S3/S4 on a regional level.

This research explores the underappreciated traditional cold-water baths of Western Anatolia, once integral to the region’s agrarian culture. Due to waves of change, which had markedly begun by the pandemic in 2019 and the aftermath of the 2020 Samos earthquake, there has been a growing interest in living in peri-urban areas, resulting in the invasion of agricultural grounds by new construction, mainly including detached houses with gardens. Such a harsh growth not only threatens the fertile lands, but also the irreplaceable cultural heritage they embrace. In this regional frame, this study focuses on three surviving baths within the Karaburun Peninsula, casting light on their current precarious state as relics of a diminishing rural way of life and local heritage. The traditional cold-water baths, constructed amidst agricultural fields for seasonal use in select villages throughout İzmir, stand as unique exemplars of rural architecture. Characterised by their singular domed chambers and their reliance on water from adjacent wells, these structures today face abandonment and disrepair. Through a multi-disciplinary lens blending ethnography, oral history, and spatial analysis, this paper portrays these unassuming yet culturally impactful baths, elucidating their intrinsic value within the heritage domain. The inquiry contributes significantly to the heritage conservation discussion, highlighting the broad spectrum of values beyond mere historical interest. By articulating the symbiotic relationship between heritage and its community, this research underscores the pressing need to weave these baths into the fabric of current social structures, safeguarding their place within the collective memory.

Miracle tales are almost the sole source for the investigation of the emergence and spread of the relic cult in the early phase of Chinese Buddhism. The earliest excavated relic casket dates back to 453 CE, over four centuries after Buddhism was introduced to China. Through a critical textual analysis of Ji Shenzhou Sanbao Gantonglu, it is evident that the initial form of relic veneration was based on miraculous responses. Legends about imperial relic worship before the 3rd century are all later fabrications. Two archeological finds—the alleged relic murals in a Han tomb at Horinger, Inner Mongolia, and the stūpa-shaped bronze vessel in Gongyi, Henan—are not directly related to relic veneration. Based on the available evidence, it is tentatively concluded that relic worship first emerged around the 3rd century in the vicinity of Luoyang, the capital of the Western Jin, and later spread to the south of the Yangtze River after the Yongjia chaos. The early worshippers included both monks and lay Buddhists, such as merchants and lower-ranking officials. Royal interest in relics did not arise until the 5th century. The rise of relic veneration in China occured two or three centuries later than that in Gandhāra, from which Chinese Buddhism was significantly influenced. Compared to the cult of images or scriptures, relic veneration also emerged relatively late in China. The reluctance to adopt relics as worship objects can be partly explained by (the mahāyāna) Buddhist doctrines and the Chinese cultural mentality. Full article

The Po Nagar Towers (Thap Ba) complex, an iconic heritage site of Cham culture and a nationally recognized special relic, has stood in Nhatrang, Vietnam, for over a thousand years. We report here a preliminary analysis of original ancient Cham bricks from the Po Nagar Towers using a combination of appropriate characterization techniques, including X-ray fluorescence (XRF), X-ray diffraction (XRD), Raman micro-spectroscopy, thermal dilatometry, compressive strength testing, and water sorption. Mechanical properties and firing temperatures of the ancient bricks have been determined to support the discussion on the likely technology used to make them. Specifically, they were made from clay, sand, plagioclases/feldspar, and grog mixed with intentionally added carbon precursor (charcoal powder), then fired at temperatures between 800 °C and 1000 °C to form lightweight bricks with a mass density of 1.3–1.6 kg/dm³ and an open porosity of 18–25%. The ancient Cham bricks have their texture and porosity to meet the requirements of the thin rubbing joint technique in tower construction and to contribute to the carvability and durability of Cham towers. A comparison is made with the bricks for tower restoration during the 2000s. Full article

Ting, Tai, Lou, and Ge are types of ancient buildings that represent traditional Chinese architecture and culture. They are primarily constructed using mortise and tenon joints, complemented by brick and stone foundations, showcasing traditional architectural craftsmanship. However, research aimed at conserving, inheriting, and rejuvenating these buildings is limited, despite their status as Provincial Cultural Relic Protection Units of China. Therefore, the aim of this study was to reveal the spatial distribution of Ting, Tai, Lou, and Ge buildings across China, as well as the factors driving differences in their spatial distribution. Tourist experiences and building popularity were also explored. The spatial analysis method (e.g., Standard deviation ellipse and Geographic detector), Word cloud generation, and sentiment analysis, which uses Natural Language Processing techniques to identify subjective emotions in text, were applied to investigated the research issues. The key findings of this study are as follows. The ratio of Ting, Tai, Lou, and Ge buildings in Southeast China to that in Northwest China divided by the “Heihe–Tengchong” Line, an important demographic boundary in China with the ratio of permanent residents in the two areas remaining stable at 94:6, was 94.6:5.4. Geographic detector analysis revealed that six of the seven natural and socioeconomic factors (topography, waterways, roads, railways, population, and carbon dioxide emissions) had a significant influence on the spatial heterogeneity of these cultural heritage buildings in China, with socioeconomic factors, particularly population, having a greater influence on building spatial distributions. All seven factors (including the normalized difference vegetation index, an indicator used to assess vegetation health and coverage) were significant in Southeast China, whereas all factors were non-significant in Northwest China, which may be explained by the small number of buildings in the latter region. The average rating scores and heat scores for Ting, Tai, Lou, and Ge buildings were 4.35 (out of 5) and 3 (out of 10), respectively, reflecting an imbalance between service quality and popularity. According to the percentages of positive and negative reviews, Lou buildings have much better tourism services than other buildings, indicating a need to improve services to attract more tourists to Ting, Tai, and Ge buildings. Four main types of words were used with high frequency in the tourism reviews collected form Ctrip, a popular online travel platform in China: (1) historical stories; (2) tourism; (3) culture; and (4) cities/provinces. Ting and Tai buildings showed similar word clouds, as did Lou and Ge buildings, with only the former including historical stories. Conversely, landmark was a high-frequency word only in the reviews of Lou and Ge buildings. Specific suggestions were proposed based on the above findings to promote tourism and revive ancient Chinese architecture. Full article
