Haus Busch was built in early medieval times, although the exact date is unknown. Today it is still unfinished, as planned reconstruction in the 18th century was not completed. The entire house is rectangular and encloses a large courtyard. The first owner, as far as can be ascertained, was the land-owner Beissel von Gymnich. In the 15th century ownership was transferred via marriage to Michael von dem Bongart. At the end of the 17th century the building was acquired by the von Groote family, who also planned the grandiose reconstruction which was never completed. In the mid-19th century Haus Busch was sold to a wealthy individual, whose descendants are the present owners.
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.
