This volume explores the transformative role of digital cultural heritage in shaping sustainable cultural tourism. It examines how innovations such as 3D reconstructions, immersive media, and memory twins—digital counterparts of monuments and artefacts—enhance visitor engagement and protect fragile sites. By linking physical heritage with digital narratives, the book demonstrates how technology fosters informed, meaningful tourism experiences while addressing challenges like overtourism and environmental stress. Featuring peer-reviewed contributions from the EuroMed2024 workshop under the UNESCO Chair on Digital Cultural Heritage, it bridges theory, policy, and practice. This resource offers scholars, policymakers, and practitioners actionable insights into managing cultural tourism in the digital era, aligning heritage preservation with the United Nations’ 2030 Agenda for Sustainable Development.
