The choir, with its flat chevet, and the transept crossing date from the 13th century and are both rib-vaulted. The nave and side aisles have ceilings and date from the 16th century. The bell tower was built at the end of the 19th century on the south-west span. The previous bell tower had burnt down in 1895. The current bells, dated 1897, bear witness to this reconstruction.
