 Accordingly, the town was fortified, with the construction of a tower on the eastern side, called today the "Clock Tower" or "Civic Tower".About 15th century, in front of it, is built the pretty little church of San Biagio.Slightly late, is the small church of the decentralized hamlet of San Maurizio, in late Gothic style (about half of the 15th century), where it seems to be here the remains of queen Sophia, daughter of Theodore II, Marquess of Montferrat and 2nd wife of emperor John VIII Palaiologos.
