The Castle is the Smithsonian’s first home and its symbolic heart. Located on the south side of the National Mall in downtown Washington, D.C., the building today symbolizes the Smithsonian and is its most recognized, built artifact on the Mall.
It was designed by James Renwick, Jr., under the direction of the Smithsonian’s first Secretary Joseph Henry. When completed in 1855, the building housed all the Smithsonian’s operations including research and administrative offices, lecture and exhibition halls, a library and reading room, chemical laboratories, storage areas for specimens, and living quarters for Joseph Henry and his family. It has served as the headquarters of the Smithsonian since then.
In 2026, the Castle will temporarily pause renovation and reopen from May 22 to September 7 as part of Our Shared Future: 250 programming to commemorate and celebrate the nation's founding in 1776. The Castle will serve as the Smithsonian Visitor Center and feature a visitor information desk, café, shop, and a special exhibition, American Aspirations.
