The Grammont Priory is a former priory of the Grandmont Order, founded by Richard the Lionheart in the 12th century. It is located in Chassay, within the commune of Saint-Prouant.
Among the best-preserved and most complete priories of this order in France (only missing the cloister), it is owned by the Vendée department and open to visitors.
Long thought to have been founded by Richard the Lionheart in 1194, the actual foundation date of the priory is likely slightly later. The construction of the buildings occurred around the same time, circa 1200. The architecture, remarkably well-preserved, is very consistent.
The chapel's vault was replaced by the current framework in the 17th century. In 1772, the Grandmontain order was abolished by the commission of regulars, and the buildings were converted into an agricultural enterprise until they were acquired by the municipality in 1985.
Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
A pleasant 30 minute-walk through the vineyards between Vufflens-le-Château and Denens, offers a stunning view of this magnificent castle, the lake and the Mont-Blanc.
