The United States Department of the Interior (DOI) is one of the executive departments of the U.S. federal government headquartered at the Main Interior Building, located at 1849 C Street NW in Washington, D.C. It is responsible for the management and conservation of most federal lands and natural resources, and the administration of programs relating to Native Americans, Alaska Natives, Native Hawaiians, territorial affairs, and insular areas of the United States, as well as programs related to historic preservation. About 75% of federal public land is managed by the department, with most of the remainder managed by the Department of Agriculture's Forest Service. The department was created on March 3, 1849. The department is headed by the secretary of the interior, who reports directly to the president of the United States and is a member of the president's Cabinet. The current secretary is Deb Haaland. As of mid-2004, the department managed 507 million acres (2,050,000 km2) of surface land, or about one-fifth of the land in the United States. It manages 476 dams and 348 reservoirs through the Bureau of Reclamation, 424 national parks, monuments, historical sites, etc. through the National Park Service, and 544 national wildlife refuges through the Fish and Wildlife Service. Despite its name, the Department of the Interior has a different role from that of the interior ministries of other nations, which are usually responsible for police matters and internal security. In the United States, national security and immigration functions are performed by the Department of Homeland Security primarily and the Department of Justice secondarily. The Department of the Interior has often been humorously called "the Department of Everything Else" because of its broad range of responsibilities.

The Interior Museum is a museum operated by the United States Department of the Interior and housed at the Department's headquarters at the Stewart Lee Udall Main Interior Building in Washington, D.C., on the first floor.When the Interior Museum opened in the U.S. Department of the Interior's newly-constructed headquarters in the nation's capital on March 8, 1938, a museum was considered a novel element to include in a federal office building. However, the Secretary of the Interior at that time—Harold Ickes (1874-1952)—was a proponent of the arts and also strongly believed in the importance of having the American people understand the work of the Department. To this day, the Interior Museum's mission remains to actively educate and inspire employees and the public about the ongoing stewardship of the nation's public lands, natural resources, and cultural heritage. The Interior Museum's collection contains more than 8,000 objects of historical, cultural, and scientific importance relating directly to the activities of the Department. In addition to developing exhibitions and public programs, Interior Museum staff also conduct public tours highlighting the elements that made the Stewart Lee Udall Department of the Interior Building a "symbol of a new day" during the Great Depression. The headquarters building contains more New Deal-era murals than any other government building, featuring such artists as John Steuart Curry, Maynard Dixon, William Gropper, Allan Houser, Velino Herrera, and Millard Sheets, plus a series of photomurals by Ansel Adams.

It was installed in 1874, but relocated several times between 1880 and 1931. The statue was sculpted by French-American artist Joseph A. Bailly, whose best known work is the statue of George Washington in front of Independence Hall in Philadelphia. The bronze sculpture, which rests on a granite base, is one of the city's eighteen Civil War monuments that were collectively listed on the National Register of Historic Places in 1978. The monument and park are owned and maintained by the National Park Service, a federal agency of the Interior Department.

Art Museum of the Americas (AMA), located in Washington, D.C., is the first art museum in the United States primarily devoted to exhibiting works of modern and contemporary art from Latin America and the Caribbean. The museum was formally established in 1976 by the Organization of American States (OAS) as the Museum of Modern Art of Latin America. Artists represented in the AMA's permanent collection include Carlos Cruz-Diez, Candido Portinari, Pedro Figari, Fernando de Szyszlo, Amelia Peláez, and Alejandro Obregón. The art collection of the OAS was initiated under the organization's Visual Arts Unit, beginning with the first donated artwork by the Brazilian neo-realist artist Portinari, in 1949. In the following decade the Permanent Council of the OAS determined to establish an acquisitions fund, in order to build up a permanent collection of artworks by significant contemporary artists from the member states of the OAS. A number of works were also purchased from or donated directly by artists, after the temporary exhibitions periodically held at the OAS gallery. The Art Museum of the Americas itself was established in 1976 by OAS Permanent Council resolution, on the occasion of the United States Bicentennial. The museum opened in what was formerly the official residence of the OAS Secretary General, a Spanish Colonial-style structure designed in 1912 by the architect Paul Cret. Initially the permanent collection held some 250 artworks, expanding over the next quarter-century to over 2000 items of painting, sculpture, installations, photography, and drawing, from the early 20th century and onwards. In addition to its permanent collection of mainly Caribbean and Latin American art, AMA hosts temporary and special exhibitions from across the region, and provides educational seminars and lectures from invited speakers. The Art Museum of the Americas has also expanded its programs to include evening events, such as Art After Dark, with cutting edge music, video, performance, and installation art.
