The parish church is the city's oldest, founded in 752 though rebuilt in Romanesque style in 1184; the façade was added in 1514. The best of the 15th century frescoes are in the Chapel of San Martino and the Chapel of Santa Caterina, which also has the sarcophagus of Manfredo I Pio. The impressive bell tower is 49.5 m high.
This was consecrated in 1500, suppressed in 1798 but re-established in 1817. In the adjoining church of 1694 lies the monastery's founder Camilla Pio.
Fine 16th century church; the convent was active until 2019.
Built from 1248 with a friary. It was modified in 1681 when it acquired the facade and its "orientation" was reversed, to face west; the bell tower was added in 1689. The church was badly damaged by the 2012 earthquake.
Built in 1450 but rebuilt in 1772. The Chapel of Madonna dell'Aiuto at the foot of the left nave is a famous Marian shrine. The bell tower is barricaded off for repairs after the earthquake. See also the nearby necropolis.
Built in 1578 but gravely damaged by the earthquake, so a new church is under construction, called Holy Trinity.
