Kohren Castle, also known as Chorun or Sahlis, is the ruin of an imposing hill castle in the town of Kohren-Sahlis in Leipzig county in Saxony.
The origin of the town Kohren can be traced back to the time of the Sorbian settlement in the Early Middle Ages. Emperor Otto II gifted the forest between the rivers Saale and Mulde to the Bishop of Merseburg in year 974.
The castle was owned by Kohren family from the late 12th century, but i was destroyed in 1220 during local wars. The current towers were built after that, but it was again demolished during the mid-15th and 17th centuries.
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.
