The chapel of the commandery also served as a parish church, and was located in the Fort; the commander appointed to the cure. The church was rebuilt in the 16th century by reusing the south wall of the old commandery building to the north. In 1668, it consisted of a nave of 3 bays with bell tower and a south chapel of 2 bays, built during a very close campaign and whose vaults rest on the same pillars. No complaint was made after the Wars of Religion. The half bay of the choir has moldings from the end of the 16th or the beginning of the 17th century. In 1857, the south vessel was increased by a west bay under the direction of L. Vigier, architect in Villeneuve-sur-Lot. In 1873, the architect Gélas redone the roof. In 1895, restoration and expansion work was carried out by Gallet, entrepreneur, under the supervision of Bouillet, architect in Marmande: construction of the bell tower, the narthex with the chapel of the baptismal font (caps pasticant those of Saint-Jean-de -Balerme), sacristies, with an additional bay to the east; the diocesan edifices committee requested a reduction in the project (height, decoration of the spire, removal of the gable of the porch and of the statue at the top).
