Six young Narnese cavers unearthed the site in 1979. Since then, a large group of volunteers has been recovering and enhancing it. In the striking 13th-century underground church, dedicated to Archangel Michael, you will relive its historical phases thanks to a multimedia system while admiring recent archaeological discoveries. The church, likely built on older structures, was incorporated into the Dominican Convent around the 14th century. The entire complex was looted in 1860 and destroyed during World War II. During the years of abandonment, rainwater covered the numerous frescoes with limestone, which are now slowly coming back to light thanks to recent restorations. It was reconsecrated in 2000 with the name St. Mary of the Cliff, since the original dedication had not yet been discovered.
In the adjacent room, thanks to an interactive video, one can learn about the systems of aqueduct excavation in Roman Narnia by virtually entering the tunnel. The heart of the underground preserves the dungeons of the Holy Office, established to combat heresies, of which one cell remains intact. Thanks to the Vatican Archives, it was possible to reconstruct the history of some of the prisoners, who left their testimony graffitied on the walls of a narrow cell. The tour continues to discover the upper church with the precious Byzantine mosaic of Narnia's first cathedral and numerous other remains and frescoes. This will not be the usual guided tour: you will not be mere spectators but protagonists of incredible events!
