In the 14th century, the Romanesque apse was replaced with a polygonal choir.

During the French Wars of Religion, the abbey was destroyed and the relics were burnt.

The reconstruction works started in 1609 and probably ended around 1670 when the new vault was installed.

The Medieval church still has remnants of the portal and the base of the nave's walls.
