site of an older church in 1099–1118; the interior was modernized in 1693, but was restored to its original form in 1902. It contains a fine ciborium in the Cosmatesque style and a 12th-century mosaic pavement. The Gothic church of Santa Maria Maggiore, in the lower town (13th-14th century), has a very fine exterior; the interior, the plan of which is a perfect rectangle, has been spoiled by restoration. Other religious edifices include the Benedictine church of San Valentino (mostly remade after World War II, but still including 13th-century frescoes) and the Romanesque monastery of Sant'Antonio Abate, which housed the remains of Pope Celestine V until 1327. The latter's heart is preserved in the small convent church of the Clarisse (17th century). In 2021, Italy's Minister of Culture awarded €1.5 million to fund the first full excavation of the town's Roman theatre, which will be partially restored for community use.
