Washington Monument plus memorials to Lincoln, MLK, FDR, WWII & Vietnam vets along a grassy mall. The National Mall is a national park in downtown Washington, D.C., the capital of the United States. The National Park Service (NPS) administers the National Mall, which is part of its National Mall and Memorial Parks unit. The term National Mall commonly includes areas that are officially part of West Potomac Park and Constitution Gardens to the west, and often is taken to refer to the entire area between the Lincoln Memorial and the United States Capitol, with the Washington Monument dividing the area slightly west of its midpoint. A smaller designation, sometimes referred to as the Mall proper, excludes both the Capitol grounds and the Washington Monument grounds, applying only to an area between them. The National Mall contains a number of museums and memorials and receives approximately 24 million visitors each year.
