It was built on the remainings of some buildings dating back to the second half of C.I, but the transformation into church very probably dates back to the era under Giustino II (567-578). It was often restored during the centuries. In 847, probably due to a earthquake, the church was abandoned but not forgotten. During C. XIII the church of S. Maria Liberatrice welled up on its ruins, where according to the legend Silvestro I defeated a dragon. The restoration of the antique S. Maria and the consequent demolition of the most recent church was decided in the early C. XX. The interior is based on three naves with small chapels in the end of the minor naves. Very interesting are also the two niches that can admire by the sides of the hall, probably dating back to the period before the collapse in C. IX.
