Église Notre-Dame de Simorre, Gothic church in Simorre, France

Église Notre-Dame de Simorre is a former abbey church in the Gers, built from 1292 under abbot Bernard II de Saint-Estier and consecrated on 8 October 1309. Its west front shows two builds side by side: a pale stone wall with a single rectangular window and stepped gable, and a red-brick section with a pointed portal ringed by nested moldings, tall traceried lancet windows and a circular opening. A brick tower with a pyramidal spire rises at the right; a black metal cross on a stone pedestal stands before the brick facade. Viollet-le-Duc's restoration of 1844–1858 gave the walls their continuous crenellation.

The church traces its origins to a 5th century chapel dedicated to Saint Cérats. The site underwent substantial rebuilding in later centuries before its formal consecration in 1309 established it as a regional religious center.

The church keeps the name Notre-Dame-de-l'Assomption and is also called Saint-Cérase, after the 5th-century evangelist honoured in the legendary founding attributed to Clovis. The Confrérie du Rosaire was installed in the Sainte-Dode chapel in 1602. Jean Marre, a Simorre merchant's son who became bishop of Condom in 1497, commissioned the choir stalls.

The church stands in the village centre of Simorre, in the Gers. The south porch, cleared of the Sainte-Dode chapel between 1898 and 1901, is the main entrance to look for. The building is a classified Monument historique, listed since 1846. The wall paintings in the sacraire, found in 1964, date from the early 14th century.

The fortified look visitors see today is largely the work of Eugène Viollet-le-Duc, who between 1844 and 1858 replaced the low-pitched roof with roofing laid directly on the vaults and added continuous crenellation along the walls. He also built watch turrets on the buttresses of the chevet and north transept. Critics soon noted that the pre-1846 roofs resembled those still seen at La Romieu and Fleurance.
