The new Church of S. Maria in Setteville was built on a large tract of land covering almost 4,000 metres on the far northern side of the district, facing Via Leopardi. The new building is unusual for its striking architectural beauty, yet is different when compared to other modern churches in the diocese because while it was being built it was discovered to be lying on the site of the ancient Via Cornicolana road.
The section of paved road discovered was in excellent condition and has been perfectly integrated into the place of worship. Part of the road is to be found in the open air, surrounded by greenery, while another section is in a large crypt underneath the sacristy and the hall, visible thanks to a specially devised project creating an archaeological museum.
The Via Cornicolana Road Museum displays remains, some of which are particularly important, recovered by the Carabinieri Task Force safeguarding Cultural Heritage, the Group Safeguarding the Archaeological Heritage from the Italian Financial authorities and the State Police, in collaboration with the Judiciary.
The permanent exhibition of objects aims to offer the visitor an opportunity to reflect on a specific issue, namely the seemingly unstoppable illegal digs and illegal trade in archaeological findings. The area between the Nomentana and Tiburtina roads in the Province of Rome also falls victim to this kind of illegal activity.
