Zelem Castle was a knight's moated fortress located in the lowland areas left of the Rhine River between the villages Mehr and Niel. Zelem was mentioned for the first time in the 12th century as a property of Echternach Abbey. In the first half of the 14th century, Zelem belonged to the Counts of Kranenburg but was sold in 1348 to the lords of Groesbeek. In the 15th century, the Palant-Wylich family became the owners of the estate, in whose hands it remained for centuries. The castle remains privately owned and can therefore only be viewed from the outside.
The castle's basic fabric comes mainly from the first half of the 15th century. In the middle of the 16th century it was rebuilt in Renaissance style. The former three-storey building includes two corner towers formerly equipped with canopies, one of which was decorated with a frieze with sandstone ornaments, mythical creatures, human heads, and a stair tower. The Renaissance portal is adorned with the emblem of the Palant family and the date 1464.
Inside the house is a barrel-vaulted basement, a tower room with a star vault, and a fireplace from the Renaissance. By 1800, the basic structure had been significantly reduced, and the fortification, except for the main wing, was dismantled.
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.
