Another incredible find courtesy of my infatuation with StumbleUpon.
The Bauhaus Archive / Museum of Design in Berlin is concerned with the research and presentation of the history and impact of the Bauhaus (1919-1933), the most important school of architecture, design, and art of the 20th century.
It is the most complete existing collection focused on the history of the school and all aspects of its work and is accessible to all. The collection is housed in a building drafted by Walter Gropius, the founder of the school.
Not surprisingly, they have a simply designed and aesthetically awesome website. My favorite part remains the Bauhaus Shop. Am I superficial with an international, design centric eye? Nevertheless, this site is worth more than a glance for the friendly navigation and curation. Libraries and museums can take notes.
