Duomo (Cathedral)

The cathedral, built in the 11th and 12th centuries, was remodeled inside at the beginning of the 13th century, and is remarkable for the combination of Lombard Romanesque style with the high vaulted ceiling more common to later Gothic architecture. Also unusual are the two staircases built into the side walls leading up to the two bell towers. The interior has 13th- to 14th-century frescoes from Venetian, Lombardian, and late Gothic schools. Under the cathedral are the remains of an early Christian basilica (sixth century), with a fine mosaic floor. The Council of Trent met in the church from 1545 to 1563, and in the south aisle, the Alberti chapel contains a large crucifix, in front of which the decrees of the Counter-Reformation were announced at its close.
