A castrum is mentioned on the site of Château de Flamarens in 1289, and is believed to have been remodelled in the 14th century. Additional building work and alterations were made some time between 1469 and about 1475 by Jean de Cazanove for Jean de Grosolles. The northern part was built before 1536 by Georges Dauzières for Arnaud de Grossolles. Alterations were made to the windows and interior decoration in the 18th century. The castle was partially destroyed by fire in 1943.
The castle is privately owned.
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.
