The Wolkenstein Castle developed historically by joining various older structures together. The tower with living quarters is the oldest part of the castle dating back to the 14th century, which was preceded by fortifications of unknown appearance. The kitchen building was expanded in the 16th century by the current dominating building parts: the South and North wings with gate house. Although much hints to the once necessary fortifications, the building ensemble is now considered a residence.
The museum at Wolkenstein Castle will give the interested visitor further glimpses into the history of the building and the city.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.
