This 13C Gothic church of Saint Peter and Saint Paul, made of sandstone, was built on the site of an earlier Romanesque church, whose square bell-tower is the only remaining feature. Inside, note the 11m/36ft-high fresco of St Christopher, dating from the 15C and the oldest painted figure known in France, and some stained-glass windows dating from the 13C. The magnificent Gothic cloisters against the north wall of the church were never finished.
