Learn About the Smithsonian CastleThe Smithsonian Building known as the Castle was designed as a home for the Secretary of the Smithsonian Institute. Today the Smithsonian Castle houses the Smithsonian's administrative offices and a visitor center with maps and interactive displays.
The designer, James Renwick, Jr., was a prominent architect who went on to build the elaborate Gothic Revival St. Patrick's Cathedral in New York City. The Smithsonian Castle has a medieval flavor with rounded Romanesque arches, square towers, and Gothic Revival details.
When it was new, the walls of the Smithsonian Castle were lilac gray. The Triassic sandstone turned red as it aged.
