Composed of a flat chevet and four chapels, the Chapelle de l'Arrier dates from the 12th and 17th centuries. It was bought and rebuilt by the Brotherhood of White Penitents. Today, this building is classified as a historic monument. We can see the old Gothic vaulting and the two-bay wall bell tower and triangular pediment, which has, nevertheless lost a bell. We also see two engraved escutcheons, and the remains of tombstones.
