The Smithsonian Castle, at 1000 Jefferson Dr SW on the National Mall, is the Smithsonian Institution’s original building and administrative headquarters. Its red Seneca sandstone, towers and Gothic Revival details stand out among the Mall’s lighter-colored buildings. The Enid A. Haupt Garden wraps around the Castle, with paths and distinct garden areas to explore. The building has also served as a visitor center, with information to help plan visits to Smithsonian museums. Renovation work has affected public access, so check its current status before planning to go inside.
The Smithsonian’s first building
The Smithsonian Institution Building, better known as the Castle, was completed in 1855. New York architect James Renwick Jr. designed it in a Victorian Gothic style, using red Seneca sandstone that gives the building its distinctive color. Its towers, varied windows and castle-like outline make it easy to pick out along the National Mall.
The building was the Smithsonian’s first home. It initially served as a museum and as a residence and workplace for the Institution’s first secretary, Joseph Henry. As the Smithsonian grew into a network of museums and research facilities, the Castle became its administrative headquarters. It remains closely associated with the Institution’s beginnings.
What to see around the Castle
The Enid A. Haupt Garden occupies the grounds beside the building, between the Castle and Independence Avenue. Its layout includes the Parterre, Moongate Garden and Fountain Garden. Plantings change through the seasons: spring brings flowers such as magnolias, flowering cherries, hyacinths and tulips, while annuals and perennials add color in summer.
The grounds give you a way to see the Castle’s red sandstone walls and architectural details even when interior access is unavailable. Take time to walk around the building and through the garden rather than treating the Castle as only a quick photo stop.
Planning an indoor visit
The Castle has served as a Smithsonian visitor center, helping people find information about the Institution’s museums and plan their time on the Mall. When public areas are accessible, indoor displays and staff can help orient you; guided tours may also be available. James Smithson, whose bequest founded the Institution, is buried in a crypt in the building’s North Tower.
Renovation work has affected access, and reports about reopening have not been consistent. Check the Smithsonian’s current building information before setting aside time for an interior visit. If the doors are closed, the exterior and garden remain the main reasons to stop.
