Immersive digital reconstruction using AR and holograms in Metaponto and Canosa di Puglia

Tangible and intangible cultural heritage today faces accelerating threats of degradation and disappearance. This research explores the use of Augmented Reality (AR) and holographic modelling to document and enhance archaeological heritage in fragile contexts. Interactive 3D models were developed using modelling software and AR platforms, and applied to the archaeological sites of Metaponto (Matera) and Canosa di Puglia. At Metaponto, AR integrated the existing ruins with stratigraphic reconstructions, improving the understanding of historical and spatial sequences. At Canosa, it enabled the virtual restitution of lost architectural elements, offering immersive experiences and educational tools. The results demonstrate that AR and holograms strengthen both research and dissemination, expanding physical and virtual accessibility to sites not yet included in established cultural networks.
