For more than 75 years, the Interior Museum’s mission has been to inspire and educate Departmental employees - as well as the general public - about the ongoing stewardship of the nation’s public lands, natural resources and cultural heritage.
The Museum gallery is open to the public, Mondays through Fridays, from 8:30 AM to 4:30 PM (closed Federal holidays). Advance reservations are required for building tours given on Tuesdays and Thursdays at 2PM. The Museum, tours, and public events are free of charge. Upon entry, guests are required to present a photo ID and pass through security.
