Château de Villers-Châtel, built in the 14th century, belonged to the lord of Gournai during the siege of Arras in 1414. The family Habarcq owned the castle until the middle of the 17th century. After several owners, Nicolas Mazel Leval bought the chateau in 1747 and restored it. During the World War I, the castle was converted into a field hospital.
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.
