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.
