The entrance has a Romanesque porch crowned by a flamboyant Gothic gable. Built from the 12 to the 16C, the church is dissymmetrical: the right-hand side is Romanesque and the left-hand side, chancel and transept are flamboyant. Du Guesclin's heart is kept in the left aisle of the transept. The modern stained-glass windows were made by the Barillet workshop.
