Rabenstein Castle is the smallest medieval castle in Saxony. It is located in the Chemnitz suburb of Rabenstein and belongs to the Chemnitz Castle Hill Museum.
The hill castle Rabenstein was first mentioned in 1336 in a document from Louis IV, Holy Roman Emperor in which he promised it as a fief to his son-in-law Frederick II, Margrave of Meissen, in case the line of Waldenburg were to die out without male heirs.
At this time the castle was larger than the current. The castle walls consisted of a 180 m long wall, which enclosed an area of two hectares.
References: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.
