The Nuragic civilization, which flourished in Sardinia between the Bronze Age and the Iron Age (ca. 1800–800 B.C.), left an archaeological legacy of extraordinary importance, evidenced by iconic monuments such as nuraghi, tombs of giants and sacred wells. This study analyses and enhances the village of Serra Orrios, a paradigmatic example of Nuragic architecture and social organization, through an integrated methodological approach combining advanced photogrammetric survey techniques, 3D modelling and augmented reality. The project produced detailed site documentation, including an updated planimetric map, and developed an AR application to improve public enjoyment and understanding of the heritage. The multidisciplinary approach highlighted the potential of these technologies for conservation, communication, and education and outlined research perspectives, including cultural comparison, sustainability, and methodological replicability. The case of Serra Orrios thus emerges as an experimental model for archaeological heritage management and enhancement.
Digital Modelling, Immersive Fruition and Divulgation of Pre-nuragic Altar of Monte d’Accoddi
This paper presents an integrated methodology for the documentation, reconstruction, and inclusive dissemination of the Pre-Nuragic archaeological site of Monte d’Accoddi in Sardinia through digital modelling, immersive environments, and visual communication. The research combines bibliographic analysis, drone-based photogrammetric survey, GIS georeferencing, point-cloud generation, mesh processing, and 3D modelling to create an accurate digital representation of the stepped altar and its surrounding ritual landscape. Starting from this common knowledge base, the authors develop multiple outputs tailored to different audiences: metric drawings and conservation panels, virtual reality guided tours, augmented reality experiences with reconstructive hypotheses, and low-tech visual journalism illustrations for users with limited digital literacy. The project also visualizes the chronological evolution of the site, including the earlier red temple, the later stepped temple, and the current archaeological remains. The study argues for a balanced approach where digital and analogue tools complement one another, enhancing accessibility, education, and public engagement with prehistoric heritage.
