It was built as a prestige mansion of the supreme burgrave of the Kingdom of Bohemia and president of governorate Jan Rudolf Chotek (1748–1824) from 1806 to 1824. The architectural scheme was drawn up by Saxon royal architect Christian Franz Schuricht (1753–1832) from Dresden. Johann Philipp Jöndl (1782–1870) and in the last few years also had controlled running the construction. He also eminently influenced the final appearance of the castle.

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.
