As part of a detailed investigation project focused on the painting materials and technical features used in Wallachia during the 17th and 18th century, the imperial icon “Mother of God with Child” from the Orthodox Church of the “Annunciation” in Râmnicu Vâlcea, Romania, was investigated before the restoration intervention. A minimally invasive multi-analytical approach consisting of high-resolution digital radiography, hyperspectral imaging, UV fluorescence imaging, portable X-ray fluorescence, and Fourier transform infrared spectroscopy was used. The results emphasized several key features, such as: the structure of the wooden panel, the nature of pigments and of the painting technique frequently used at that time, and various defects of the pictorial layer including traces of previous restoration works, most probably made at the end of the 18th century.

Pollutant gases pose a significant risk to some cultural heritage objects, and surveys have shown that the professionals involved consider themselves to lack knowledge to fully assess risk. Three approaches towards risk assessment, research results, standards and damage functions have been considered. An assessment tool has been developed, collating over 4000 research reports into a scheme for the impact on 22 materials of acetic and formic acids, nitrogen dioxide, ozone and reduced sulphur gases. The application of doses or concentrations has been considered, the impact of measurement time compared to annual exposure investigated and a simple tool derived. Full article

Using rock art conservation as a focus, this paper outlines the levels of legislated protection afforded to designated natural and cultural areas/sites in Australia and describes the co-management approach adopted in 1998 in relation to Mutawintji National Park in western New South Wales. The park encompasses four different protection categories: a Historic Site, a Nature Reserve, a National Park, and a State Conservation Area. Known for more than a century, the Historic Site is a major area of rock art containing Aboriginal engravings, paintings and stencils. Management of the Historic Site is a key concern, given the tourist interest and associated potential for accelerated deterioration of cultural heritage. The Mutawintji Plan of Management pointed to the importance of Mutawintji for Aboriginal people to connect with the country, and the co-management model encouraged tourism development as a means of providing employment opportunities as Aboriginal guides. No special legislative requirements in relation to rock art conservation, beyond those already in existence, were applied to the co-management system. Using field knowledge involving rock art research and early guide training programs at Mutawintji and literature sources, this paper suggests possible future approaches to rock art conservation in the Mutawintji Lands.

The employment of technology and digitization is crucial for cultural organizations to establish and sustain digital repositories for their cultural heritage artifacts. This exploitation is also essential in facilitating the presentation of cultural works and exhibits to a broader audience. Consequently, in this work, we propose a custom-developed digital repository that functions as software-as-a-service (SaaS), primarily promoting the safe storage, display, and sharing of cultural materials; enhancing accessibility; and fostering a deeper understanding and appreciation of cultural heritage. The proposed digital repository service is designed as a multitenant architecture, which enables organizations to expand their reach, enhance accessibility, foster collaboration, and ensure the preservation of their content. Moreover, our technology stack incorporates robust and reliable backend technologies, such as Django, to ensure data security and efficient management. Meanwhile, the frontend is powered by Angular, which guarantees a user-friendly and engaging interface for exploring and interacting with cultural materials. Specifically, this project aims to assist each cultural institution in organizing its digital cultural assets into collections and feeding other digital platforms, including educational, museum, pedagogical, and games, through appropriate interfaces. The creation of this digital repository offers a cutting-edge and effective open-access laboratory solution. It allows organizations to have a significant influence on their audiences by fostering cultural understanding and appreciation. Additionally, it facilitates the connection between different digital repositories and national/European aggregators, promoting collaboration and information sharing. By embracing this innovative solution, cultural institutions can benefit from shared resources and features, such as system updates, backup and recovery services, and data analytics tools, attributes that are currently provided by the platform.

Cultural heritage governance and management has been shifting from the sole authority of the state and public bodies towards approaches that list multi-actor partnerships in several combinations involving public actors, civil society, private actors and community. This paper examines the public–civil, public–private and public–private–community partnerships through expounding rationales, conceptual backgrounds and theoretical framings for each partnership, followed by a systemic review and analysis of the academic literature sourced through the PRISMA protocol. The analysis objective was to assess the main advantages and disadvantages of each of the partnerships in governing and managing cultural heritage, noting the levels of representation of each governance and management approach. The results have shown that the public–civil and public–private–community partnerships have similar advantages and disadvantages, with the public–civil partnership being the least represented approach in the literature, while the public–private partnership has the highest level of representation with advantages and disadvantages that are inclined towards more pragmatic aims than those of the other two examined approaches. The so-called ‘new governance models’ of heritage were also detected in the analysis; however, they represent only a variant of the already analysed models. Full article

This review paper aims to provide a meta-analysis of the scientific literature for heritage documentation and monitoring using geo-information sensors. The study initially introduces the main types of geomatic sensors that are currently widely used for heritage studies. Although the list provided here is indicative rather than exhaustive, it provides a general overview of the variety of sensors used for different observation scales. The study next focuses on the existing literature, based on published documents. Targeted queries were implemented to the Scopus database to extract the relevant information. Filtering was then applied to the results so as to limit the analysis on the specific thematic sub-domains that is applied for heritage documentation and monitoring. These domains include, among other close-range and underwater photogrammetry, Terrestrial Laser Scanner, Unmanned Aerial Vehicles platforms, and satellite observations. In total, more than 12,000 documents were further elaborated. The overall findings are summarized and presented here, providing further insights into the current status of the domain. Full article

This paper describes the operations carried out to generate a georeferenced heritage inventory at a supra-municipal scale. The tool establishes links between its heritage elements based on the features and characteristics of the territory. The work has been carried out on the fluvial zone of the Lower Guadalquivir, an area of approximately 8500 km² located in Andalusia in the south of Spain. The method used is based on the digital inventory of the Andalusian immovable historical heritage generated by the Andalusian Institute of Historical Heritage, in which more than 500 heritage assets in the study area are indexed. The work begins with the expansion and processing of these assets with the aim of reorganizing them and establishing new parameters in their classification schemes. Subsequently, a spatial analysis developed in a GIS environment detects relationships between heritage assets determined by the physical characteristics of the territory. These relationships are contrasted by historical research, and eight heritage networks in the territory are defined as a result. Finally, one of the networks is used to show how, from the graph theory, it is possible to investigate the detected links. Ultimately, it is discussed how this study allows us to move toward new models of the heritage management of territorial dimension and relational vocation. Full article

The process of coming out of the COVID-19 pandemic is an opportunity to create various scenarios for returning to the path of tourism development. The search for suitable and effective solutions was at the heart of the Tourism Friendly Cities project, in which eight European cities participated. The aim is to define the challenges and tools related to the sustainability of urban tourism. The empirical research was based on the opinions of experts from eight cities involved, and concerned four thematic areas: the quality of life and tourism in the city before and during/after COVID-19, tourism dysfunctions, the sources of conflicts between local stakeholders, and the tools for the sustainable reconstruction of tourism. The results confirmed the existence of a wide range of declared tools for the development of sustainable tourism after the pandemic. The conducted research indicates key areas of conflict in the field of tourism activity. The authors also come to the conclusion that tools for regulating tourist traffic should not be universal, but should meet the individual needs of the city. Full article

This paper presents a preliminary scientific investigation of pigments used by Martiros Sarian, a prominent Armenian artist known for his vibrant and evocative paintings. The study focuses on five of Sarian’s paintings from different periods of his career, namely, Morning in Stavrino, Arabian Dancer, Caravan, Yerevan Zangu River, and Kirovakan, dated between 1909 and 1948. Non-destructive techniques, including micro-attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopic imaging and X-ray fluorescence (XRF), were employed to characterize the pigments in the samples extracted from these paintings. The results reveal the presence of various pigments, including ultramarine blue, cobalt blue, cobalt cerulean blue, viridian, emerald green, cobalt green, celadonite green, cadmium yellow, chrome yellow, Venetian red, yellow ochre, red ochre, lead white, zinc white, and calcium carbonate. Additionally, metal carboxylates and oxalates, degradation products associated with the paint layers, were observed and discussed. The findings contribute to a better understanding of Sarian’s artistic technique and provide valuable insights for the conservation and restoration of his artworks. Full article

The Natural History Museum of the University of Pisa hosts one of the most important osteological collections of cetaceans all over Europe, as well as a conspicuous paleontological collection, including several holotypes of Archaeoceti (archaic whales), Mysticeti (baleen whales), and Odontoceti (toothed whales). In order to valorize these collections, we used 3D technologies to digitize the most relevant specimens, create an online archive, and make the resulting models accessible and shareable with the broadest audience possible through social media profiles and internet browsers. Tens of specimens were surface-scanned using a structured-light scanner, and the resulting 3D models were processed for post-production through the 3D software Blender whenever necessary. All the 3D scans were then gathered in the online repository Sketchfab, which was chosen for its user-friendly interface and common usage among museum institutions. The result is a web page that hosts 35 surface scans of extant and extinct cetacean specimens. This Sketchfab account was linked to the social media (Facebook and Instagram) profiles of the MSNUP to increase the visibility of the museum and promote the dissemination of its outstanding collections of modern and fossil cetaceans. The preliminary results of such an effort are encouraging in terms of views and online interactions. Hopefully, this effort of digitization and online archiving will soon extend to other vertebrate collections. Full article

Military tourism has been growing in Portugal in recent years with numerous initiatives to enhance and promote the country’s military and historical heritage. In the academic context, studies have emerged to consolidate the segment in the tourism activity. In this framework, INSIGNIA was born, a project aimed at monitoring, evaluating and optimizing the Military Tourism Route. The implementation of the route and the network-based strategies chosen to structure the supply have been monitored to register key insights gathered through this model of heritage asset intervention and tourism development. This paper proposes a reflective overview of the implementation and monitoring processes, a lookback at the work conducted. Firstly, proposes a reflection on the implementation process, tracing its genesis in response to the conjunctures of the structuring of tourism supply and the consolidation of the concept itself. It seeks to reflect on the specific choices and services developed during the implementation process. Based on this lookback, the authors then propose a replicable model to guide these implementation processes. Using the monitoring experience of this study as a reference point, the model suggests possible metrics, as well as proposals for the collection and analysis of data relevant to its wider application.

In recent times, the significance of living heritage during crises has gained prominence. While the aftermath of such crises often leads to lessons being forgotten, those in conflict zones persistently endure hardships. This study examines the pivotal role of intangible cultural heritage (ICH) in bolstering resilience, particularly among diaspora communities, using Syrians in the UK as a case study. We delve into the primary ICH practices that they adopt, their assimilation techniques within the UK, the impact of wartime experiences on their reactions to the COVID-19 pandemic lockdown, and the consequent effects on host communities. Employing a diverse methodological framework that includes online public lectures, interviews, and direct observations, our results underscore the Syrian diaspora’s earnest commitment to preserving its rich heritage. Beyond the poignant losses of invaluable art and treasures to conflict, a dominant narrative of hope and enduring human spirit emerges. As illuminated by our findings, Syrians’ resilience extends beyond mere survival, reflecting a deep-seated pride in identity and an unyielding cultural spirit. This resilience not only marks the continuation of Syrian culture but also highlights its capacity to evolve, adapt, and enrich new environments. Full article

Historic Building Information Modelling (HBIM) is the application of BIM, a digital modelling and information management technique, to assets of historical significance, otherwise known as Cultural Heritage (CH). The adoption of BIM for CH is justified by government mandates and acknowledgement by leading heritage institutions that there is a need to utilise digital tools for heritage management. This paper establishes the current state of HBIM implementation within CH as well as research trends to date via a review of the existing literature. Geometric modelling was found to be the topic of very early research into HBIM, with particular focus given to improving the accuracy and efficiency of modelling. Thus, methods for improving modelling were evaluated. HBIM as an information management tool is discussed including the issues encountered, such as data storage and insufficient existing tools, as well as key information requirements proposed in the literature. An evaluation of key HBIM case studies found limited evidence of the created models being used in practice and an overall lack of consideration of the information needs. It was determined that the implementation of HBIM is limited by a lack of defined information requirements, and standardisation regarding the method of implementation. Full article

Earthquakes are hard to predict, and the destruction caused by the events far outstrip the monetary damage. Important cultural heritage sites functioning as places of community and identity have a value which evades pure pecuniary calculation. This makes understanding the complete economic and social impact of earthquakes a difficult and daunting task. We use high-resolution TerraSAR-X data acquired after the 2023 earthquake in Turkey to assess its impact on selected cultural heritage sites. Leveraging different orbit and incidence angles of image acquisition allow us to show the difficulties in interpreting high-resolution SAR data. While large impacts, like the complete collapse of structures, can be detected successfully, small-scale damage and partial collapses are often difficult to detect from single SAR images. We find that single SAR scene interpretation for damage assessment of cultural heritage is not a viable option. While contextualizing data might help to understand the situation, SAR is only helpful if data of the intact cultural heritage sites have been obtained before the event. Full article

Cultural heritage sites can be affected by landslides, often causing damage to their integrity, value, and accessibility. Several studies worldwide were focused on the assessment of the potential threats that landslides can pose to the preservation of cultural heritage sites. This article aims to review landslide studies at cultural heritage sites worldwide, analyzing the publications’ temporal distribution, selected methods, geographical and climate contexts, and investigated landslide types. We analyzed a database of 331 publications from 2000 to 2023 in study areas distributed across 47 countries, compiled through systematic queries of the Web of Science and Scopus catalogs. The results show an increase in the number of publications from 2012 onwards, with most studies performing landslide susceptibility analyses on cultural heritage sites. The majority of the studies deployed a geomorphological approach address slope instability mechanisms that threaten site integrity, with a significant number of publications presenting model-based, multidisciplinary and engineering geological approaches. Europe, North America, and Asia and the Pacific concentrate the majority of studies, with Italy and China having the highest number of case studies. The threats to cultural heritage sites located in Latin America and the Caribbean, and Africa are the least studied. Block slides, earth slides, and rock falls are the most studied processes, with fewer studies dealing with other landslide types. Full article

Pottery is a complex archaeological material that is found ubiquitously in various spatial—temporal frameworks from all over the world; therefore, it is of great importance to archaeological research. The current paper aims to present and discuss the results obtained on a batch of Neolithic (ca. 6000–5000 BC) and Chalcolithic (ca. 5000–3900 BC) pottery sherds from Southern Romania through X-ray Computed Tomography, a non-destructive methodology that allows for the 3D reconstruction and precise measurement of inclusions and voids present within ceramic artefacts. Images from several potsherds were subsequently exported and analyzed by means of dedicated software (ImageJ 1.54p and GIMP) to extract quantitative information on the observed features. Grain size and morphometric analyses were performed on the particles, while the contour variability of the examined inclusions was characterized through the application of shape descriptors. Voids were analyzed in order to reveal specific orientation patterns through the examination of the aspect ratio of the holes and of the Rayleigh z test values. These analyses evidenced the general reliance of moderately and poorly sorted clays for ceramic production, accompanied by a gradual transition from organic to grog tempering, while conservative traditions remained prevalent in primary pottery-forming processes.

Demographic and economic shrinkage has become a common trend in the current urbanisation environment, especially for small cities in developed countries. The desired socio-economic redevelopment of these cities has been significantly affected by the functional, organisational, financial, and professional constraints caused by both shrinkage and city size. Paradoxically, this slow development has enabled better preservation of their historic cores, urban heritage, and traditional culture. Nevertheless, the aforementioned local constraints have a profound impact on sustainable urban regeneration, and successful examples are still quite rare. This research presents an inspiring case—a small museum quarter in Sombor, Serbia. Museum quarters are a relatively new concept in culture-led urban regeneration; all known examples are located in big cities. Hence, this research tries to create an innovative methodological link between two theoretical fundaments: the role of cultural heritage in shrinking small cities and its expression through a museum quarter as one of the concepts of culture-led urban regeneration. An analytical framework for the aforementioned single case study is derived by forming this link. The main findings underline that the museum quarters in shrinking small cities should be developed in a micro-format to rationally address and the limited local resources. Furthermore, in contrast to museum quarters in big cities, they should be physically detached from the main retail street to enhance their separate identity and should be internally balanced in both spatial and functional aspects, meaning that the key museum/cultural institutions are equally dispersed throughout the quarter and clearly interconnected by a pedestrian-friendly open public space.

Aotearoa/New Zealand was first settled by the Māori people some 800–1000 years ago. Archaeomagnetism provides one of the few means of dating early sites of Māori occupation, particularly when radiocarbon dating is not feasible. This involves dating the thermoremanent magnetization imparted to the heat-retaining stones used in traditional Māori earth ovens, hāngī or umu, at the time of their last cooling. The direction of this magnetization is correlated with the reference curve of the changes in the geomagnetic field direction in New Zealand over the past 1000 years, NZPSV1k.2023. Here, we describe the application of archaeomagnetic dating to indigenous hāngī sampled at two sites in the North Island of New Zealand. The first, in the present-day city of Napier on the east coast, has been studied in detail and is shown to have been occupied, possibly intermittently, over 400–600 years, while the second, in present-day Waikanae on the west coast, is tentatively dated to ca. 1760 AD, just decades before the first European arrival in New Zealand.

This paper presents current findings about the historical use of silver and metallic elements as part of the decorative technique from Colombia known as barniz de Pasto. The results are part of broader ongoing research. The aim is to interpret and assess the introduction of metal as a significant component in the consolidation of the technique. Our research uses well-established imaging techniques (visible light macrophotography; infrared and ultraviolet photography), cross-sections, and elemental mapping from SEM-EDS. The results are compared and interpreted within a holistic framework suggesting the introduction of silver as part of an innovation of the barniz de Pasto technique, either as whole silver leaf sandwiched between layers of mopa-mopa or as “venturine”, obtained by kneading, and therefore fragmenting, silver leaf within mopa-mopa layers.

Historical documents are often severely damaged, making it impossible to open them manually without causing further damage. To address this challenge, computed tomography (CT) has emerged as a non-destructive method to explore the inside in a different way. However, the use of ionising radiation in CT scanning raises concerns about its impact on fragile historical documents. This study presents a methodology that uses a test object to conduct preliminary investigations to evaluate the capability of a CT scanner for digital preservation of historical documents. By assessing the feasibility and determining the setting parameters in advance, the X-ray exposure to historical documents can be minimised. For this purpose, a large dataset of inter-page distances was obtained from CT scans of a specially developed test object. The results obtained show a consistent correlation between the page-to-page distances and the derived modulation depths. This method offers great potential for assessing the separability of the pages of historical documents even before they are exposed to radiation for digitisation. Overall, this study helps to reduce the impact of X-ray radiation on sensitive historical documents during digitisation using CT, with the aim of preserving this fragile cultural heritage for future generations.

Cova de la Sarsa (València, Spain) is one of the most important Neolithic impressed ware culture archaeological sites in the Western Mediterranean. It has been widely referenced since it was excavated in the 1920s, due partly to the relatively early excavation and publication of the site, and partly to the qualitative and quantitative importance of its archaeological remains. Unfortunately, as it was an older excavation and lacked present-day rigorous methodological approaches, this important site has been somewhat relegated to the background in the reviews about the Neolithic at the end of the 20th century. However, during the last few years, both the site itself and its archaeological remains have been the object of new studies that hopefully will return the site to the forefront of discussions about the Mediterranean Neolithic. We here present the most relevant results of the research carried out by our group (i.e., pottery study, radiocarbon dating, and isotope analysis), and contextualize them within the dense research history of the cave and the studies carried out by other colleagues with the purpose of revisiting its materials and increasing the knowledge available from the site. Radiocarbon dates on human remains show that the cave was used during prehistoric times as a funerary space longer than expected, and also sporadically afterwards. The characterization of the pottery assemblage concludes that most materials belong to the Early Neolithic. Isotopic analysis portrays an overall similar diet based on terrestrial C₃ resources throughout prehistoric times, with a possible varied dietary protein input between individuals during the Early Neolithic.

A fundamental step in the best preservation of heritage materials is investigating their chemical and physical characteristics, and understanding how they interact with the surrounding environment. For this reason, the stone masonry of the monumental UNESCO site of Panamá Viejo was subjected to a thorough study to characterize the materials and evaluate their state of conservation. Additionally, potential outcrops were explored in order to identify sites for the supply of raw materials. The methodological approach encompassed mineralogical-petrographic investigations using stereomicroscopy, polarized light microscopy (PLM), X-ray powder diffraction (XRPD), scanning electron microscopy and energy dispersive X-ray spectrometry (ESEM-EDS) and X-ray fluorescence (XRF). The results revealed that the masonries primarily consists of polygenic breccia, basaltic andesite, rhyodacite, tuffite, and rhyolite. In addition, at the potential quarries, breccia and basaltic andesite were identified. The porous structure was studied using mercury intrusion porosimetry (MIP). Possible issues due to salt dissolution/crystallization cycles were considered. Consequently, ion chromatography (IC) was conducted on samples exhibiting alteration patinas to study the presence of soluble salts. In assessing the state of conservation, prevalent forms of deterioration included biological colonization, detachments, material loss, potential salt weathering, and chromatic alteration. In conclusion, the outcomes of this work provide a valuable resource for the current and future preservation of this site. Full article

Mid-19th century maps of Tróia Peninsula (Grândola) indicated the existence of a site named “Fishermen’s huts” on the beach. The site was partially excavated in 2019 and presents the characteristics of a village where around a dozen vernacular architecture shacks accommodated people who lived there between approximately 1860 and 1920. The architecture, material culture, and settlement location reveal the presence of a population with specific social and cultural characteristics related to an amphibious or hybrid lifestyle between the land and the sea. This paper presents this community, considering the relation of the people living there with the surrounding environment (natural and cultural resources) and relations within the community, where it was possible to recognize different genders and identities. These considerations are framed within social, economic, and cultural concepts. Full article

For a number of years, heritage resources have suffered the negative effects of tourist pressure. Overtourism has been generating a wide-ranging debate on this issue. This work focuses on the strategies and measures adopted to address overtourism during the last 30 years at heritage attractions, which are much less studied than urban heritage centres. Specifically, it analyses measures relating to the management of site capacities based on the concept of tourist carrying capacity, using content analysis as a methodology. We have used the Alhambra in Granada as a case study as one of the most visited Spanish World Heritage Sites. The results obtained reflect a strong consensus on the need to introduce measures to restrict tourist activity, although these measures imply a great effort in terms of management and tend to be taken advantage of by some stakeholders for their own benefit. The extensive time frame of the measures adopted allows us to reflect on the possibilities and limitations of dealing with overtourism by using capacity management strategies and to extract useful conclusions for other heritage sites with similar problems.

This research presents an application of the Building Information Modelling (BIM) methodology to the preservation of buildings of historic value. The study of the built heritage encompasses several aspects: namely, the collection of information, the rigorous representation of the building, the identification of the applied traditional construction processes, and the classification of historic eras of construction, conservation or refurbishing. In a BIM context, the topic of old buildings is referred to as Heritage Building Information Modelling (HBIM). In order to illustrate the type of work that needs to be prepared, a building heritage case is presented. The study is focused on the identification of the historic evolution of a castle and the adjacent structural environment. The first step concerns the data collecting: several institutional repositories of old documents were consulted; technical visits to the site were performed; a large photographic survey was undertaken; and photogrammetry technology was applied. Based on the available information, the corresponding stratigraphic HBIM model of the historic complex was generated, which was associated with an accessible and well-organised database. This text aims to contribute positively to the dissemination of the HBIM in the preservation of historic buildings, and it is focused on a mandatory first step: generating a complete stratigraphic HBIM model. The model is intended to be a useful support to professionals to elaborate the preservation project, as it archives relevant data. The description of all processes from the data collection to the stratigraphic model brings an important understanding of the relevance of a primary stage performed with depth and care. This research contemplates, essentially, the topic of collecting data as essential to the performance of heritage studies. Full article

Neglected and abandoned heritage sites are a complex research topic, which always requires a thorough understanding of the site’s past and current condition. This article examines how research on history, architecture, and participation can contribute to creating a suitable re-use project for such heritage sites, focusing on a single case study: the Royal Citadel of Messina, Italy. Within the field of history, the city and fortification’s past underscores the importance of the site’s architectural and historical value. An urban analysis and documentation campaign were carried out during the field architecture. The urban analysis focused on the site as a remarkable natural landscape with industrial surroundings. The digital documentation, concentrating on the so-called cistern, emphasized the site’s values. Within a revalorization process, community participation is vital and is, therefore, one of the suggestions to consider in further developments. The last applied method is a comparative case study, namely, the submarine base at Saint-Nazaire, France. Considering the complexity and fragilities of the site, a framework is designed that provides suggestions for the conservation, revalorization, and re-use of the site of the Royal Citadel.
