Abstract
The hypogeum of San Salvatore di Sinis (Sardinia, Italy) is one of the oldest signs of the presence of the first Christians in Sardinia (IV century a.C.). Its walls are finely decorated with drawings from different periods, today strongly degraded. The present knowledge of the monument and of the site is not complete therefore, to check the presence of buried remains that could be related to the hypogeum, an extensive geophysical survey using ground penetrating radar (GPR), 3D ERT, seismic survey was carried out in the area around the church and inside it. The walls and floor of the hypogeum were also investigated. The results of the survey shown numerous buried structures in the surround of the hypogeum, furthermore some other voids are probably present near the hypogeum.
The data collected were used to implement a tool that can be utilized both to explore the subsoil and to see the lost drawings on walls as a virtual archaeology. The system also allows the musealization and the use by disabled people.
