Abbaye Saint-Vincent de Nieul-sur-l'Autise

The foundation stone of the abbey was laid in 1069 under Airaud Gassedenier, a follower of William VIII, Count of Poitiers and Duke of Aquitaine. The foundation was intended for a community of Augustinian canons, who played a role in the drainage and development of the Marais Poitevin. In 1076, the endowment was confirmed by the Count-Duke. King Louis VII elevated the abbey to a royal institution in 1141. Aénor de Châtellerault, the mother of Eleanor of Aquitaine, found her final resting place here. In 1568, the complex suffered destruction during the Wars of Religion. Its later preservation and restoration in the 19th century are partly thanks to Prosper Mérimée. However, a tower added in the 19th century over the Romanesque portal altered the original appearance of the facade.

The monastery is located in Nieul-sur-l'Autise in the Vendée department in the Pays de la Loire region, France, at an elevation of approximately 13 meters above sea level.

Today, the Abbaye Saint-Vincent de Nieul-sur-l'Autise houses a museum. Between 2000 and 2003, the complex underwent extensive renovation, combining historic Tuffeau stones with modern materials such as steel and glass. Visitors can explore exhibition rooms featuring old musical instruments, Romanesque capitals, and the “Maison Aliénor”.
