is an unincorporated area located in Loudoun County, Virginia, west of Washington, D.C., and is part of the Washington Metropolitan Area. The area serves as headquarters for the internet service provider Verizon Business, Old Dominion Brewing Company, and the Janelia Farm Research Campus (HHMI). "Redskins Park", the headquarters for the Washington Redskins football team of the National Football League, is also located in Ashburn.
Ashburn is located between Washington Dulles International Airport and Leesburg, the county seat of Loudoun County. Located within the Dulles Technology Corridor, Ashburn is home to many high-tech businesses. World Trade Center Dulles Airport is currently under construction and will be the second World Trade Center in the state. George Washington University and Strayer University have campuses in Ashburn.
Ashburn is home to four landmarks on the National Register of Historic Places: Belmont Manor House (1799), the
) after a nearby mansion of that name owned by George Lee III. The name Farmwell first appeared in George Lee's October 1802 will and was used to describe the 1,236 acre (5.0 km²) plantation he inherited from his father, Thomas Ludwell Lee II. A section of Farmwell plantation west of Ashburn Road, a 580 acre (2.3 km²) tract, was purchased in 1841 by lawyer and almost vice-president John Janney, a Quaker, as a summer home. John Janney called the property Ashburn Farm (first known written use is 1870 when he sold the property). It is likely he named the farm after family friends named Ashburn.
In 1895, Ashburn Farm was purchased by Senator William Morris Stewart. Local legend has it that the village, known until then as Farmwell or Farmwell Station, got its new name after lightning struck an ash tree on Senator Stewart's farm in 1896. The ash tree is rumored to have burned and smoldered for a week and attracted spectators from miles around. Since the Post Office had been pressing for a new name for the village (to avoid confusion with Farmville in Prince Edward County, Virginia), and the Senator was the area's leading citizen, the villagers renamed the village after the burning ash tree.
Ashburn was also the vacation destination of many Presidents, like Woodrow Wilson, as well as many of Washington's other politicians. They would take the only Washington and Old Dominion Railroad line out to Ashburn, which contained some upscale hotels and restaurants. Most of these hotels and restaurants have long since been destroyed or dismantled, but a few can still be seen along the main street of Ashburn Road.
