The European Hansemuseum is dedicated to the history of the Hanseatic League. The museum consists of a permanent exhibition with exhibits of original historical objects, interactive elements and staged historical scenes from the former trading ports of the Hansa Novgorod, Bruges, Bergen and London, as well as Lübeck. The original historical items displayed include documents, paintings and gold and silver coins from the so-called Lübeck Hoard.
The exhibition is aimed at informing visitors about the overall history of the Hanseatic League from its formation to its dissolution, but also about the economics and trade networks of the League as well as of everyday life in the historical time span during which the Hansa existed. It is the largest museum in the world dedicated to the history of the Hanseatic League.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.
