The manor, first mentioned in 1523, was for a longer period of time associated with the noble family of von Ungern-Sternberg. The Neo-Baroque castle, constructed on the manor grounds in 1890 (a copy of the Merseburg castle in Germany), was never finished. After World War II the manor fell into the hands of Soviet troops, in 1968 the chief of the airport decided to use the ruins of the manor to fill in the holes in the runway. About one third of the manor was torn down, fortunately the rest was preserved until today.
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.
