Ulvsunda castle was built by Field Marshal Lennart Torstensson between 1644-1647. His family owned the estate until 1727. Since them Ulvsunda has been owned for example by Bielkegatan ,Gyllenkrook , Rudenschöld and Ruuth families. Baron von Essen bought it in the early 1800s and the current appearance dates from the restoration made in 1830s. Today Ulvsunda is a hotel, restaurant and conference centre.
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.
