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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
