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.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
