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.

The sculpture is one of three outdoor artworks in Washington, D.C. by Whitney, the other two being the Titanic Memorial and the Aztec Fountain at the Pan American Union Building.

The Van Ness Mansion was completed for John Peter Van Ness and Marcia Van Ness in 1816 by Benjamin Henry Latrobe on 17th Street, Washington, D.C. They entertained the Madisons, James Monroe, George Washington Parke Custis and John Tayloe III at their mansion. The mansion was described as the "finest house in America". It was built on land that had been owned by Marcia's father, David Burnes, who left 500 acres along the Potomac River to Van Ness. It was one of the most expensive houses in the country, fit with hot and cold running water, a modern feature at the time, and the mansion was the first residence in the city to have that luxury. Latrobe added a feature designed to maintain a sense of privacy when food was conveyed to dining rooms. Servants accessed rotating servers from a hallway that allowed them to deliver food without entering the room. He installed them previously at the Adena Mansion in Chillicothe, Ohio. It had the country's largest and coolest wine vault. Latrop said that the Van Ness Mansion was "the best house I ever designed". It overlaid his "American rational-configuration on the kind of English residential model that impressed him during his work for and study with S. P. Cockerell."Latrobe also worked with John Peter Van Ness on the reconstruction of Washington, D.C. public buildings. Van Ness was a commissioner of the Capitol reconstruction commission, along with Richard B. Lee and Tench Ringgold. The mansion degraded over time. In 1907, the mansion was razed and the Pan American Union Building was built on the site. The stables, also designed by Latrobe, were not demolished at that time. The stuccoed building existed was located at 18th and C Streets.
