The Bauhaus-Archiv Museum für Gestaltung is a Berlin museum entirely dedicated to the Bauhaus movement. It is located in the Tiergarten district, in a building built by 1979 on a project by Walter Gropius himself, founder of the movement. Opened in 1960, it was initially located in the city of Darmstadt, only to be moved to Berlin in 1971. The Museum preserves the most complete collection of documents on the history and function of the Bauhaus, one of the most important schools of architecture, art and design of the twentieth century. The collection contains didactic material used by the school, architectural models and projects, photographs and various documents. There are also several design objects, including some well-known such as the Bauhaus lamp and the Wassily chair. The museum also organizes temporary exhibitions that delve into the history of the movement and its activity. Conferences, outdoor exhibitions, readings and concerts are also organized. In the museum there is also a library that collects more than 26,000 works including books, magazines, catalogs, manuscripts and letters.
