Under a large dome topped with a skylight, this 13C church, reconstructed in 1574, was transformed into a cathedral after its reconstruction. In the form of a Greek Cross, the interior is home to Renaissance baptismal fonts and recesses with iron grilles where well-born ladies could attend services without being obliged to mingle with the common people. Also note the attractive sculpted oak throne and a large wooden triptych attributed to the Genoese painter Barbagelata (1458) representing the Annunciation.
