The church is preceded by an ashlar bell tower-porch, with three pointed-arch openings. The first level is cross-vaulted. Three sides are pierced by geminated campanary arcades with semicircular arches resting on chisels and a central pilaster. The ashlar southwest chapel, supported by a buttress, rests against the west facade. Next door, the sacristy is lower than the chapel. Flat, gable-less chevet. The building has undergone many alterations, starting with the 19th-century bell tower.
