Forse Castle ruins dates from c. 1200 in the hamlet of Forse. The castle stands on a peninsula about 50 metres above sea level. It is surrounded on all sides by steep rocks and is cut off from the mainland by a natural ditch at the neck of the peninsula. Forse Castle was the stronghold of the Sutherland of Forse family, a cadet branch of the Clan Sutherland. They lived in it until around 1600.
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.
