Smithsonian Institution Building

  Smithsonian Institution Building stands proudly at 1000 Jefferson Drive SW in Washington, D.C., also known as the "Castle" due to its distinct Richardsonian Romanesque architecture. Completed in 1855, it serves as the heart of the Smithsonian Institution, a complex that spans 19 museums and galleries, emphasizing education and research. Visitors can explore its beautiful interior, which features lush gardens and several exhibitions that showcase the Institution's extensive collections. Throughout April, families often join special workshops and activities designed to engage children in the arts and sciences. With its red sandstone exterior and inviting atmosphere, the Smithsonian Institution Building is not only a notable landmark but also a hub of cultural exploration in the National Mall area.
