Official Guide of Arlington, VA: www.stayarlington.com
Arlington County is an urban community of about 26 square miles located directly across the Potomac River from Washington, D.C. No incorporated towns or cities lie within Arlington’s boundaries. Originally part of the 10-mile square surveyed in 1791 for the nation’s capital, the portion on the west bank of the Potomac River was returned to the Commonwealth of Virginia by the U.S. Congress in 1846. This area was known as Alexandria City and Alexandria County until 1920, when the County portion was renamed Arlington County.
While perhaps best known to visitors for its wealth of tourist destinations, Arlington is an outstanding place to live and work. The County’s central location to the metropolitan area, its ease of access by transit, car, and airplane, its high quality residential neighborhoods, and its top-notch labor force have attracted a wide range of businesses and residents, helping our community grow and thrive.
Along with being the home of the Pentagon, the Marine Corps War Memorial (Iwo Jima), Arlington National Cemetery, and the United States Air Force Memorial, Arlington County is home to approximately 216,700 people. The County’s population is among the most highly educated in the nation and is increasingly diverse. It is estimated that one in four residents is foreign-born, with one in three speaking a language other than English at home.
