Today, Fort Belvoir is home to a number of important United States military organizations. With nearly twice as many workers as The Pentagon, Fort Belvoir is the largest employer in Fairfax County. Fort Belvoir comprises three geographically distinct areas: main base, Davison Army Airfield, and Fort Belvoir North.



The Fort Belvoir site was originally the home of William Fairfax, the cousin and land agent of Thomas Fairfax, 6th Lord Fairfax of Cameron the proprietor of the Northern Neck, which stood on land now part of the base. William Fairfax purchased the property in 1738 when his cousin arranged for him to be appointed customs agent (tax collector) for the Potomac River, and William erected an elegant brick mansion overlooking the river, moving in with his family in 1740. Lord Fairfax came to America in 1747 and stayed less than a year at the Belvoir estate before moving to Greenway Court. The Fairfax family lived at Belvoir for over 30 years, but eldest son (and heir) George William Fairfax sailed to England on business in 1773, never to return. The manor home was destroyed by fire in 1783.

The ruins of the Belvoir Mansion and the nearby Fairfax family grave site are listed on the National Register of Historic Places.


The post was founded during World War I as Camp A. A. Humphreys, named for Union Civil War general Andrew A. Humphreys, who was also Chief of Engineers. The post was renamed Fort Belvoir in the 1930s in recognition of the Belvoir plantation that once occupied the site. The adjacent United States Army Corps of Engineers Humphreys Engineer Center retains part of the original name.

Fort Belvoir was initially the home of the Army Engineer School. Beginning in 1987, the Engineer School relocated to Fort Leonard Wood, in Missouri, and was formally transferred the following year.[2]

As a result of the 2005 Base Realignment and Closure Commission, a substantial number of personnel were transferred to Fort Belvoir, and others were civilians employed there. All major Washington, DC-area National Geospatial-Intelligence Agency (NGA) facilities, including those in Bethesda, MD; Reston, VA; and Washington, DC, were consolidated at a new facility, the NGA Campus East, situated on the former Engineer Proving Ground site.[3] The cost of the new center was $2.4 billion.[4]

The Army Historical Foundation announced in March 2017 that construction will soon begin on the National Museum of the United States Army on Fort Belvoir. The museum, set on 84 acres, will tell the story of the army since 1775. The 185,000 square-foot museum will feature historical galleries, an "interactive Experiential Learning Center" and the Army Theater. There will also be outdoor venues including a Memorial Garden, Amphitheater, Parade Ground, and Army Trail. It is expected to open in late 2019.[5]
