Interior Museum

The Interior Museum is a federal museum in downtown Washington, D.C., housed within the Stewart Lee Udall Building. It displays collections documenting the nation's land management and conservation history.

The museum opened in 1938 shortly after the building's completion during President Franklin D. Roosevelt's New Deal era. The structure itself reflects the architectural style and government expansion of that 1930s reform period.

The museum displays how the government has managed conservation and public lands over many decades. Visitors can see how this work has shaped the landscapes and communities across the country.

The museum operates on weekdays and is located in a federal building that requires photo identification for entry. Visitors should use the C Street lobby as the entrance and allow time to explore the galleries.

The building contains numerous murals throughout its corridors and galleries depicting natural resources, indigenous peoples, and conservation efforts. These artworks reflect the ideals and vision of the 1930s reform movement.
