Laufenburg is a castle located in the municipality of Langerwehe in the state of North Rhine-Westphalia. The castle was first mentioned in historical records in the 13th century and is believed to have been built in the 12th century. It is a typical example of a medieval hill castle, with a rectangular keep and a surrounding wall with four corner towers.
Throughout its history, Laufenburg has been owned by a number of noble families, including the Lords of Heinsberg and the Dukes of Jülich. In the 20th century it was restored after been damaged in the World War II. Today it has an restaurant.
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.
