The Cathedral of Bisaccia, located a short walk from the ducal castle of Bisaccia, was built by the Normans on a site not far from the present one. Razed to the ground three times by the frequent earthquakes that struck Bisaccia over the centuries, the present church was finished in 1747, using part of the materials of the previous building.

The church was first destroyed by the earthquake that affected Irpinia in 1456, but the people’s will was to start the renovation work immediately, which ended in 1515, as confirmed by a Latin inscription visible on the Cathedral’s stone portal. Then the building was destroyed on two more occasions in 1694 and 1732. After the third earthquake event it was decided to rebuild the Cathedral near the castle, using some materials from the previous building.

The three-aisled interior preserves a carved wooden choir made during the 17th century and the high altar in polychrome marble, closed by a balustrade. The Gothic-style facade, preceded by a long staircase, features a portal from 1515, surmounted by several Romanesque-Gothic bas-reliefs recovered from the building rebuilt in 1515 and a thick cornice.
