Sustainability in Cultural Heritage (CH) is a complex question that needs to be addressed by a group of experts tackling the different issues. In this light, the present work wishes to provide a multi-level analysis of the sustainability in CH, using as an example a recent European H2020 project (CrossCult) and the lessons learnt from its design, implementation and evaluation. The sustainability of CH has qualitatively changed over the last few years, under the developments in digital technology that seems to affect the very nature of the cultural experience. We discuss sustainability in venues using digital technologies, covering a span of needs of small/unknown and large/popular venues, which try to enhance the visitor experience, attract visitors, form venue networks, etc. Moreover, we explore issues of sustainability of digital content and its re usability through holistic design. Aspects of technology, human networks and data sustainability are also presented, and we conclude with the arguments concerning the sustainability of visitor reflection, the interpretation of social and historical phenomena and the creation of meaning.

The Horizon 2020 project CrossCult aims to highlight historical and cultural associations between different characters, locations, events, venues, or artworks, to develop new strategies with which to promote intercultural and cross-border aspects of history and heritage. This paper presents a pilot app that provides graph-based visualizations of those associations, arranged by Humanities experts in relation to several reflective topics, and glued together by narratives that may present the same facts from diverse points of view. After querying a knowledge base that brings together several Linked Data resources, the associations are curated by the experts using a dedicated tool, to ensure that only meaningful associations appear on the mobile app. In turn, the app users can contribute new associations in the form of written text, which the experts can turn into new concepts and properties in the knowledge base. Here, we present the design of the mobile app and the experts’ tool, together with the results of early experiments aimed at assessing the instructional value of the proposal.

In spite of the great leap forward experienced in our understanding of the use of marble and other ornamental stones in Roman Spain, provenance studies are still quite uncommon in some territories of the Iberian Peninsula. This was the case of the northwesternmost part (modern Galicia), where no significant work had been done until now. Within the framework of an interdisciplinary study, a significant number of objects studied did not match with the main well-known Classical marbles but seemed to have been produced with a local stone known as O Incio marble, which had never been yet archaeometrically analysed. Therefore, the quarries near the small village of O Incio were located and sampled, and a multi-method approach combining polarized-light microscopy, cathodoluminescence, X-ray powder diffraction and stable C and O isotope analysis as well as spectrophotometry was applied to characterize the different outcropping marble varieties as the first and basic step to correctly differentiate them from other Iberian and foreign marbles with similar macroscopic features.

The Via Francigena stands as a European Cultural Route recognized by the Council of Europe, serving as a link between Northern and Southern Europe, extending from Canterbury through France and Switzerland to Rome in Italy. The Universal Declaration of Human Rights underscores the right of all individuals to partake in the cultural life of their communities, which entails ensuring that heritage sites remain accessible to everyone, regardless of their physical, cognitive or sensory abilities. To achieve this, the ‘rurAllure’ project has been initiated to promote and disseminate the cultural and natural heritage along this pilgrimage route in an inclusive manner. This paper reviews the existing resources regarding accessibility in the Italian segment of the Via Francigena, comparing them to initiatives undertaken on other European Cultural Routes. This serves as an initial step to comprehend the measures required to guarantee that everyone can fully engage with and comprehend these cultural experiences. The analysis revealed that most of the limited accessibility efforts along this route have primarily focused on physical accessibility. Regrettably, cognitive and sensory accessibility has received considerably less attention. In this context, this paper proposes the thermal heritage located along the Val d’Orcia section in Tuscany, Italy, as particularly promising for the development of accessible experiences due to its tactile characteristics. The future efforts to enhance accessibility along this route should consider approaches like Universal Design for Learning and the geography of perception to create resources and new experiences that cater to a wide range of individuals.

Recent advances in semantic web and deep learning technologies enable new means for the computational analysis of vast amounts of information from the field of digital humanities. We discuss how some of the techniques can be used to identify historical and cultural symmetries between different characters, locations, events or venues, and how these can be harnessed to develop new strategies to promote intercultural and cross-border aspects that support the teaching and learning of history and heritage. The strategies have been put to the test in the context of the European project CrossCult, revealing enormous potential to encourage curiosity to discover new information and increase retention of learned information.
