The ruins of the Pajrek Castle (Burg Bayereck) lie above the town of Nýrsko in the western part of the Bohemian Forest at a height of 505 metres above sea level.
This important border castle was built at the beginning of the 14th century, but by 1472 it had already been abandoned. In 1504, the castle was rebuilt, but it was only used until the middle of the 16th century, when it was finally abandoned. Only the remains of the huge tower have survived.
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.
