Late-Gothic construction, it has a single nave covered by a ribbed vault and is topped by a pointed triumphal arch, which opens onto the Mannerist chancel. Inside, there are ancient tombstones and two Baroque altarpieces that came from the Cathedral. The façade, following the damage inflicted by the 1755 earthquake, was remodelled using Late-Baroque aesthetic language. On the outside, the overlifted apse is crowned with chamfered merlons and zoomorphic gargoyles.
