Kalma manor was built as a hunting lodge for Baron Fedor von Medem after he acquired the estate in 1855. It was quickly repaired after being damaged by fire in 1905. Between 1906 and 1912, it was restored according to the project of architect G. Berchi. The most recent restoration was completed in 2004, the building then being made available for public event rentals. A museum with exhibits on milk production is located in one of the other estate buildings.
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.
