Montquintin Castle was probably originally designed to defend the southern border of the counts of Chiny. It was built in the 11th century by order of Louis II, Count of Chiny (born 1025). Over the centuries the castle has undergone many changes. The central part was rebuilt the 18th centuryt by the Bishop of Hontheim, last owner. In 1869 a fire destroyed the castle. The basement includes a vaulted cellar, which is very well preserved.
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.
