Main image

The Interior Museum is the museum of the U.S. Department of the Interior located in Washington, D.C., that documents the department’s work and the natural and cultural resources it manages. It interprets the missions of Interior bureaus through art, artifacts, photographs, and maps.

Displays and temporary exhibitions highlight topics such as public lands management, conservation, Native American history and cultures, and scientific work related to U.S. natural resources. Galleries typically feature rotating shows and object loans from Interior bureaus rather than a single large permanent collection.

The museum was established to present and preserve materials related to the Department of the Interior and to educate the public about federal stewardship of land, water, and cultural resources. Over time the museum has hosted thematic exhibitions tied to policy, anniversaries, and bureau-specific collections.

The museum is housed within the Department of the Interior’s headquarters in central Washington, D.C., within walking distance of the National Mall and the Federal Triangle area.

  • Exhibitions: Exhibitions rotate and commonly draw on collections from Department of the Interior bureaus such as the National Park Service and the Bureau of Indian Affairs.
