The first known owner of Rössjöholm castle was Danish knight Olof Geed around the year 1500. Later it was owned for example by Leijonsköld, Silfverskiöld, Sjöcrona families. The first strong castle was built in 1553 and it had even seven towers. The castle was destroyed by Swedish forces in 1676, but some ruins of this castle still remains. The new main building was built in 1696, but it was destroyed by fire in 1730. The current castle dates from 1731. Since 1857 it has been owned by Rosenørn-Lehn family. The famous writer Frans G. Bengtsson was born and lived in Rössjöholm.
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.
