The ancient Desenzano castle was originally built around the year 1000. Enlarged at the end of the 15th century, the castle never became a real military fort, but served primarily as a refuge for the population. The plan of the castle is an irregular rectangle, with the tower that stands out at the entrance on the northern side, protecting the drawbridge, which loopholes for the chains are still preserved. The castle is open to the public.
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.
