Washington, D.C., is the capital of the United States. It is coterminous with the District of Columbia (abbreviated as "D.C."). The city and the district are located on the banks of the Potomac River and bordered by the Commonwealth of Virginia (to the southwest) and the State of Maryland (to the northwest, northeast and southeast). The city was planned and developed in the late 18th century to serve as the permanent national capital; the federal district was formed to keep the national capital distinct from the states.

Washington is home to numerous national landmarks and is one of the most popular tourist destinations in the United States. The National Mall is a large, open park area in the center of the city featuring many monuments to American leaders; it also serves to connect the White House and the United States Capitol buildings. Located prominently in the center of the Mall is the Washington Monument.
