Saint-Didier church was rebuilt in 1860 after the old wooden church burnt down, with its original stained glass windows. The church has an elongated floor plan, with a 5-bay, barrel-vaulted nave with three aisles. The aisles and the choir, with its flat chevet, have ceilings. In the choir, a restored painting of the Martyrdom of Saint-Didier.
