This simple Benedictine Gothic church, originally high medieval, then completely rebuilt in the 13th century, is preceded by a narthex which leads to a portal with lintel. The bell tower, detaches from the main building, is a square tower.
The interior is very interesting, in square stone blocks that alternate whit rows of bricks, a nave and two aisles divided by pillars that support ogee arches. Of the original three apses only the central and part of the right hand apse remain.
The crypt is very simple: on the left hand wall fragments of Roman and high medieval origin have been inserted, including a sarcophagus lid, a late Roman work with bas-relief biblical scenes.
