Tradition has it that Pope Leo the Great stopped Attila’s advance at a place called Forte Urbano, not far from here. Records of the previous church are inadequate but it is known to have been rebuilt in 1752-1788.

The building is baroque, faced externally with stone. In 1897, it was restored and consecrated by Bishop Origo. Further restoration in 1968 removed the 19C decorations and 18C stucco ornaments. Inside, a painting by Bazzani depicts the encounter between Attila and Leo.
