The building is characterized by its bulbous bell tower (or onion), a Baroque architectural style applied to bell towers, and its ashlar walls.
All that remains of the original 13th-century building are the choir and apse, and two 16th-century side chapels. Having become too small, lengthy reflections on the building at the end of the 19th century led to an extension in length and width, all in the neo-Gothic style so popular at the time. The end of the twentieth century saw another rejuvenation with the replacement of the damaged stained glass windows: made in the abbey of Saint-Benoît-sur-Loire, these non-figurative windows have a tone that perfectly matches the bare walls. Look up and you'll see an organ dating from 1861, listed as a Monument Historique!
