Smithsonian Institution, South Quadrangle Project

Washington, DC | 1987

A landmark project of America's national museum, the South Quadrangle was completed in 1987. Bounded by three existing Nationally Registered Landmarks - the Freer Gallery of Art, and the Smithsonian Castle - the South Quadrangle occupies one of the most prestigious sites in Washington.

The below-ground complex includes the Arthur M Sackler Gallery, the National Museum of African Art, and the S. Dillon Ripley International Center. The complex is entered through two 4,130-square-foot granite pavilions located in the 4.2 acre Enid A. Haupt Garden.

The Haupt Garden reinterprets an earlier Victorian garden on this site. Three discrete areas reflect the garden traditions of Asian, Islamic, and Victorian cultures which are represented by the new museums and the Smithsonian as a whole.

The Sackler Gallery is built on three skylit levels, extending 57 feet below ground, and houses over 8,800 objects in its collection.
