Arlington Virginia

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.
