Jever castle dates back to a weir from the late 14th century. The fortress got its typical characteristics mostly from the massive keep, which during the 15th and 16th century was surrounded by a Vierseitanlage. When Jever became part of the Duchy of Oldenburg in 1818, the castle was declared an auxiliary residence of the Dukes of Oldenburg and the now useless outbuildings and fortification were done away with. The museum has been situated in the castle since 1921 and features collections of cultural history, folklore and the archaeology of the Jever region.
The historic rooms also give an overview of the lifestyle of the 16th to 19th century. You will have the best view from the 67 meter-high castle tower. The viewing platform offers a unique view over the expanse of the Friesian coast.
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.
