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.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
