Golem Grad, also known as Snake Island, is located in Lake Prespa, a few kilometers from the Greek and Albanian border. Golem Grad is home to several ancient ruins and churches. It is also home to several different communities of animals, especially snakes.
The island is currently uninhabited and has been so since the mid-20th century, when the small monastic community left the island. The island can only be reached by boat.
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.
