Valdek is a castle ruin in the municipality of Chaloupky in the Central Bohemian Region of the Czech Republic. The name is probably derived from two German words: Wald (the forest) and Eck (a widespread part of places' names, meaning rock formation).
The castle was built around the middle of the 13th century (first written mention comes from the year 1263) by an aristocratic Buzic family. In 1623 it was described as abandoned.[1] Passing centuries left only ruins, dominated by a still standing large round tower (bergfrit), built during the second half of the 13th century.
In 1926, the area around the castle became part of the Military training area Jince. The castle itself was still accessible (except during manoeuvres). After 1950, no access was allowed. After 1989, it became possible to visit the castle again but tourists were not allowed to stray from the road to the castle.
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.
