Between 1919 and 1933, the Bauhaus School, based first in Weimar and then in Dessau, revolutionised architectural and aesthetic concepts and practices. The buildings created and decorated by the school's professors (Henry van de Velde, Walter Gropius, Hannes Meyer, Laszlo Moholy-Nagy and Wassily Kandinsky) launched the Modern Movement, which shaped much of the architecture of the 20th century and beyond.
The main building of the Bauhaus university in Weimar was built between 1904 and 1911 based on plans by Henry van de Velde. As one of the most influential art academies of the early 20th century, this is where the Bauhaus movement was founded in 1919. Today, the building is listed as a UNESCO World Heritage Site.
Under the supervision of architect Thomas van den Valentyn, the building was completely renovated and almost fully restored to its original condition in 1999.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.
