A 3D approach to the archaeological study of the built remains at the Santa Cristina well sanctuary, Sardinia, Italy

The paper presents the 3D investigation of the architectonic remains at the well complex of the archaeological site of Santa Cristina, located near the town of Paulilatino, in the province of Oristano, the Sardinian Island, Italy. The visible today remains integrate original fragments of the initial structure, built sometime 3000 years ago, and modern reconstruction conducted almost half a century ago. Despite the fact that the site has been excavated and its remains investigated for more than 50 years, no publications detailing the archaeological finds are available. The research presented here focuses on the contribution of 3D documentation and subsequent analysis of the well complex for understanding social aspects related to and reflected by the architectural remains.
