When the Staatsgalerie, designed in the Neoclassical style by Georg Gottlob Barth, opened in 1843, it was one of Germany's first museums, with a collection featuring the works of German and European Old Masters. Destroyed in World War II, the museum was reopened in 1958, rebuilt (with some modifications) according to its original plan. In 1984 a second building, designed in a postmodern style by British architect James Stirling (Stirling, Sir James) and called the Neue (New) Staatsgalerie, was completed to house the museum's 20th- and 21st-century artworks. The Alte (Old) Staatsgalerie building was further extended with an addition by the Swiss architects Wilfrid and Katharina Steib (completed 2002). This extension enabled the return of the department of prints, drawings, and photographs (which had been removed to the Crown Prince's Palace in the 1930s) and includes office space, study centres, the library, and restoration workshops.
