Bauhaus Stair by 96dpi on Flickr.
The interior of the Bauhaus in the original design had almost no signage. Colors lead the way through the building, depending largely on the color teaching of Wassily Kandinsky - one the famous teachers of the Bauhaus. The Nazi closed the Bauhaus 1933 and one of the early example for modernism was burned in the flames of a bomb strike 1945. The GDR tried to reconstruct a simplified version without some key elements like the steel and glass facade. After the German reunification the building became UNESCO world culture heritage in 1996. The extensive renovation faithfully recreated the original state from 1926, altering only minor details.
