The Roman walls, which open onto the beautiful Consular Port (1st century B.C.), protect it at the base of the hill, then the medieval village climbs up to the Capuchin Church and what now remains of the fortress, which Cardinal Albornoz had fortified in the fourteenth century.
The most sacred and significant building is the church of S. Maria Maggiore, dating from the 11th century. Within you can see the beautiful Baglioni chapel, with frescoes by Pinturicchio, who also painted the Madonna with Child in the Oratory of the Canons, adjacent to the main chapel.
Beautiful too is the Chiesa di S. Andrea (church of St. Andrew), which preserves 15th century frescoes and a crucifix on board from the 1300s above the high altar.
On Corpus Christi day in June, the impressive ''Flower Festival" takes place, when
the town’s streets are filled and adorned with beautiful flower compositions.
