The old Kronhuset (the Crown House) behind the Gustav Adolf Square is one of the oldest buildings in Gothenburg. It was built in 1642-1654 as a storehouse for military uniforms and other military equipment. Now it is a living craft center in historic buildings.
Around Kronhuset is Kronhusbodarna (the Crown House Sheds).The west wing served as carriage storage and warehouse, and was built around 1750 after the previous wooden buildings around Kronhuset burned down. The east wing was built in 1759 for artillery weapon smiths, turners and saddlers. Sweden was at this time mobilizing for war with Denmark and the demande for a warehouse in Gothenburg was therefore high.
Kronhuset was built in Dutch style, and apart from the brick walls and ceiling, it's made entirely of wood. It is six stories high and the ground floor has no supporting pillars, which means that you could more easily move around guns and vehicles.
When the parliament convened in Gothenburg Kronhuset also functioned as parliament house. Nowadays the neighborhood is a vibrant craft centre. In the small sheds the are shops for glassworks, chocolate, candy, furniture, clocks, pottery and leather. There is also a popular cafe and bakery.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.
