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. 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:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
