The Centreville Military Railroad was a 5.5-mile (8.9 km) spur running from the Orange and Alexandria Railroad east of Manassas Junction across Bull Run and up the south side of the Centreville Plateau. Built by the Confederate States Army between November 1861 and February 1862, it was the first exclusively military railroad. Ultimately, the Centreville Military Railroad reached a point near a modern McDonald's restaurant on Virginia State Route 28, south of the modern junction with U.S. Route 29 in Virginia.

Ellanor C. Lawrence Park is located in Chantilly, Virginia, just north of Centreville, on Route 28. The park preserves the cultural and natural resources of western Fairfax County and has a long and complex history lasting 8,000 years. The land was originally inhabited by Native Americans, but as Europeans settled in Virginia, the land was shaped by only three families: the Browns, Machens and Lawrences. Through these periods, the land was used as a tenant farm, family homestead, and country estate until it was deeded to Fairfax County Park Authority as a 640-acre nature park in 1971. On the eastern side of Route 28, visitors can learn about the site’s natural and cultural history at Walney Visitor Center, where visitors can see the park’s several significant structures including Walney, an 18th-century farmhouse, and 19th century outbuildings and features, including a smokehouse, dairy, ice house and ice pond remnants. Cabell's Mill and Middlegate stand in the southeastern end of the park. Middlegate is an early 19th-century stone house associated with Cabell’s Mill, which was built in the 18th century. Cabell's Mill is a popular setting for weddings and is available for rent through the Fairfax County Park Authority. Middlegate is used for park administrative offices. Approximately four miles of mostly earthen trails are accessible from the Visitor Center, the pond, Cabell's Mill and the park's northern terminus on Poplar Tree Road. The trails pass through the park's diverse habitats and are popular with birders, runners, dog walkers, and families. Trail maps are available at the Walney Visitor Center. Bicycles are not permitted on most park trails except the paved or gravel Big Rocky Run Stream Trail, which begins near Cabell's Mill and ends at the Fairfax County Parkway. Fishing under state regulations and licensing is permitted in the pond and Big Rocky Run. On the western site of Route 28, the park houses playgrounds, athletic fields (including soccer, baseball, and softball fields), and a fitness trail with stations.

Uniontown is an unincorporated community in Fairfax County, in the U.S. state of Virginia.

The Battle of Blackburn's Ford (also known as the Skirmish at Blackburn's Ford) took place on July 18, 1861, in the Confederate state of Virginia, as part of the Manassas campaign of the American Civil War. Union general Irvin McDowell's Army of Northeastern Virginia was marching south towards the Confederate capital of Richmond, and encountered the Confederate Army of the Potomac under the command of P. G. T. Beauregard. McDowell sent troops from Daniel Tyler's division to probe the Confederate defenses along Bull Run Creek to locate the Confederate left flank. At Blackburn's Ford, the Union troops attempted to cross but Confederate fire broke up the attack. The repulse at Blackburn's Ford led McDowell to seek to attack the Confederates at a different point along their line, leading to the First Battle of Bull Run three days later.

Blackburn's Ford was the crossing of Bull Run by Centreville Road between Manassas and Centreville, Virginia, in the United States. It was named after the original owner of the Yorkshire Plantation (McLean's Farm), Col. Richard Blackburn, formerly of Yorkshire, England. The land was acquired in 1854 by Wilmer McLean who owned it until 1867.

Greenbriar is a census-designated place in Fairfax County, Virginia, United States. The population as of the 2010 census was 8,166. The community between Fairfax City and Chantilly dates from the late 1960s, when it was developed by Levitt & Sons. The community is famous for having only one road within its territory that does not start with an "M" or "P", which is Acorn Hill (added in 1994 with the addition of five mansions to the community). A popular (but not proven) belief is that the roads were named after the architect's two children. One drawback for residents of the community is that with nearly identical sounding named roads (for example, Mayport and Maylock) in such close proximity to each other and house numbers being the same, the US Postal Service along with UPS and FedEx sometimes deliver items to the wrong house.

Chantilly is a census-designated place (CDP) in western Fairfax County, Virginia. The population was 24,301 as of the 2020 census. Chantilly is named after an early-19th-century mansion and farm, which in turn took the name of an 18th-century plantation that was located in Westmoreland County, Virginia. The name "Chantilly" originated in France with the Château de Chantilly, about 28 miles north of Paris. Located in the Northern Virginia portion of the Washington metropolitan area, Chantilly sits approximately 25 miles (40 km) west of Washington, D.C., via Interstate 66 and U.S. Route 50. It is located between Centreville to the south, Herndon and Reston to the north and northeast, respectively, and Fairfax 7 miles (11 km) to the southeast. U.S. Route 50 and Virginia State Route 28 intersect in Chantilly, and these highways provide access to the Dulles/Reston/Tysons Corner technology corridor and other major employment centers in Northern Virginia and Washington, D.C.

The NAVWAR Space Field Activity (NSFA) is one of three Echelon III activities under the Naval Information Warfare Systems Command (NAVWARSYSCOM) of the United States Navy, co-located with the National Reconnaissance Office (NRO) in Chantilly, Virginia. The activity was established to coordinate naval space and warfare systems activities within the National Reconnaissance Office. NSFA personnel provide naval warfare and acquisition expertise to national reconnaissance programs, coordinate naval space research, development, and acquisition activities with those same national reconnaissance programs, and provide and coordinate training and tools to enable the fleet to use national space capabilities.

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA.NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of the Washington Dulles International Airport. The Director of the NRO reports to both the Director of National Intelligence and the Secretary of Defense. The NRO's federal workforce is a hybrid organization consisting of some 3,000 personnel including NRO cadre, Air Force, Army, CIA, NGA, NSA, Navy and US Space Force personnel. A 1996 bipartisan commission report described the NRO as having by far the largest budget of any intelligence agency, and "virtually no federal workforce", accomplishing most of its work through "tens of thousands" of defense contractor personnel.
