Baldenau Castle was built by the Trier Elector and Archbishop Balduin of Luxemburg around the year 1320. Initially designed as a hunting lodge, it was later on, beginning in 1324, completed to a residential seat through the construction of additional buildings, stables, and barns. The principal Balduin who initiated the building and gave it his name, was born in 1285 as the youngest son of Count Henry VI. of Luxemburg.
The most impressive part of castle is the keep, 25m height and 10m width. The surrounding moat is 12m wide. During the Thirty Years' War (1618-1648), Baldenau Castle was seriously damaged by Swedish troops, but reconstructed throughout the years 1649-1654. However, only 35 years later, in 1689, the French army devastated the castle.
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.
