An unincorporated area in western Fairfax County, west of Washington, DC. Home to Washington Dulles International Airport and in close proximity to both the nation's capital and one of the nation's largest clusters of technology firms, Chantilly boasts a number of mid-to-lowrise hotel and office buildings.
Despite the rapid growth within the Chantilly area, there remains many remnants of Fairfax County's historic past here. Sites such as Sully Plantation, built in 1799 by Richard Bland Lee, Robert E. Lee's uncle, serve as museums for 19th century plantation life. The town of Chantilly itself saw its beginnings when a post office was established here in 1832. On September 1, 1862, the Battle of Chantilly (Ox Hill) was fought here when Major General Thomas "Stonewall" Jackson's forces led an attack on Union troops retreating from Bull Run during the Civil War. The area remained little unchanged well into the 20th century until the opening of Washington Dulles International Airport in 1962. The Smithsonian Institution's National Air and Space Museum opened its Steven F. Udvar-Hazy Center at Dulles in December 2003.
