United States Public Health Service Building

The Main Navy and Munitions Buildings were constructed in 1918 along Constitution Avenue (then known as B Street) on Washington, D.C.'s National Mall (Potomac Park) as the largest of a set of temporary war buildings on the National Mall. Both buildings were constructed by the Navy's Bureau of Yards and Docks, with the United States Department of War occupying the Munitions Building. To make the buildings more resistant to fire, the buildings were constructed using concrete. With solid construction, the temporary buildings remained in use long after the end of World War I. In August 1939, the Secretary of War relocated his offices from the overcrowded State-War-Navy Building (Old Executive Office Building) to the Munitions Building. The Department of War headquarters remained in the Munitions Building, through the early years of World War II, until 1942, when some space became available in the Pentagon, which was under construction. The Munitions Building was turned over to the Navy in 1943, when the Department of War completely vacated the Munitions Building once construction of the Pentagon was completed. Both buildings suffered serious structural problems in the 1960s. In December 1969, President Richard Nixon announced that both buildings would be demolished, a plan which was carried out in 1970. The land was then reclaimed and turned into Constitution Gardens, with the Vietnam Veterans Memorial built near the former Munitions Building site in the early 1980s.

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.
