The Château de Ramstein is a ruined castle in the commune of Baerenthal. This 13th-century castle was built by the lords of Falkenstein on the instructions of the bishop of Strasbourg to control the Zinselbach valley, probably in 1292. During the course of the 14th century, the lords of Ramstein transformed it into a den of brigands and it was destroyed in 1355 during a punitive expedition by the Strasbourgeois and their allies from Bern.
Below the castle can be seen two underground passages dug in 1936 by French military engineers as part of the Maginot Line. They were used as shelter by the local population during the battles of winter 1944-45. This site is currently closed to protect a colony of bats.
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.
