Under a large Dome topped with a skylight, the 13 C church, reconstructed in 1574, was built as a cathedral after its reconstruction. Inside, in the form of a Greek Cross, Renaissance baptismal fonts, recesses with iron grilles where well-born ladies would carry out their business without being obliged to mingle with the common people, an attractive sculpted oak throne and a large wooden triptych attributed to the Genoese painter Barbagelata (1458) representing the Annunciation.
