The existence of the parish is attested around 1240. The current church retains its Romanesque character from the original building. Almost completely rebuilt around 1407, it was disoriented and extended by 8 meters in 1836; the old choir is currently located at the bottom of the nave. The church was skillfully restored in 1972.
