Chiesa di San Giovanni
It was built between the thirteenth and fourteenth centuries, on the site previously occupied by the primitive Cathedral of St. Mariano. The Church has a Gothic facade, while the bell tower is Romanesque. The interior consists of a single nave with a square apse, while the roof is supported by stone arches on twin columns. Many of the original frescoes have been lost, there are only some fragments of St. Catherine of Alexandria and of her Mystical Marriage.
