The origins of Hrušov castle are not known, but it was probably built after the invasion of Tatars around 1253. From 1321 to 1344 it belonged to the family Levické and then became a royal property. In 1347 King Louis I of Hungary gave it to the governor Hrušov. The castle was destroyed by the Imperial army in 1708 and is in decay since then. However, its surviving walls induce a romantic atmosphere and provide a nice panoramic view.
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.
