Odenhausen Castle was first built in the 11th century on the hill. In the Middle Ages, the fortification was expanded into a moated water castle. The castle was first mentioned in 1316. In 1560 Ludwig von Blankart converted it into a Renaissance residence.
A bridge leads across the outer moat through a Baroque gate into the farmhouse and an another bridge leads over the moat to the two-winged mansion. The portal is decorated by a coat of arms.
Since 2005, the castle is owned by the Vieten couple.
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.
