The Kammerzell House is one of the most famous buildings of Strasbourg and one of the most ornate and well preserved medieval civil housing buildings in late Gothic architecture in the areas formerly belonging to the Holy Roman Empire.
Built in 1427 but twice transformed in 1467 and 1589, the building as it is now historically belongs to the German Renaissance but is stylistically still attached to the Rhineland black and white timber-framed style of civil (as opposed to administrative, clerical or noble) architecture.
It is situated on the Place de la Cathédrale, north-west of the Strasbourg Cathedral, with whose rosy colour it contrasts in a picturesque way when seen from the opposite direction.
The building's inside has been decorated on all floors by lavish frescoes by Alsatian painter Léo Schnug (1878-1933). It now houses a restaurant.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.
