Smithsonian Institution Building ('The Castle') and Smithsonian Open Access

The Smithsonian Institution Building, known as the Castle, is located at 1000 Jefferson Dr SW and serves as the Smithsonian's visitor center and administrative hub. The Castle's distinctive architecture is widely photographed by visitors, and the Smithsonian's digital initiatives-such as Smithsonian Open Access-make high-resolution images and records from its collections widely available and shared online. The institution's extensive online collections and public programs have amplified the Castle's visibility across educational and social platforms.
