The first manor on the site was built in 1666 by the Pointel family. Today the ruins of this original manor are still visible. The current Château de la Briantais was built by Eugene Sully-Brunet between 1850-1864. Today it is owned by the city of Saint-Malo and used for concerts and other events. The 27-hectares park is worth of seeing, including a chapel from 1778.
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.
