This 15th-century church has undergone several modifications, probably as a result of looting and fire. Seen from the air, it doesn't have the traditional Latin cross plan, with an eaves forming a sort of courtyard between the nave and the north chapel. Inside, only one bay has retained its original ribbed vault and fleur-de-lis keystone. The transept is not a transept, but two chapels. On the floor, you'll find a number of funerary stones, including one belonging to an abbot.
