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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
