The District of Columbia, capital of the United States, is home to 76 National Historic Landmarks. The National Historic Landmark program is operated under the auspices of the National Park Service, and recognizes structures, districts, objects, and similar resources according to a list of criteria of national significance. The city's landmarks reflect its status as the national capital, including grand government buildings, homes of politicians, military facilities, and museums. The list also includes sites relating to support for the disabled, the Civil Rights Movement, pioneering urban infrastructure, and other historic themes. National Historic Landmarks are normally listed on the National Register of Historic Places. Washington is home to three specifically legislated exceptions to this rule: the White House, the United States Capitol, and the United States Supreme Court Building. All are designated landmarks, but are not on the National Register.
