Château de Castries has belonged to the House of Castries since 1465. In 1565, Jacques de Castries undertook the building of a new château. The garden was laid out by André Le Nôtre in 1666. The aqueduct, to water the garden, was built by Pierre-Paul Riquet.
The main house was looted and damaged during the French Revolution of 1789 and was restored in 1828. In 1935, it was bought back by René de La Croix de Castries. In 1985, he donated the house to the Académie française. It is open to the public.
References: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.
