Fairfax County celebrated its 275th Anniversary on Saturday, June 17, 2017, in the area surrounding the Historic Fairfax Courthouse and the Judicial Center grounds in the City of Fairfax. More than 80 historical organizations, attractions, re-enactment units, and booths were present to showcase the county's neighborhoods, sites, and history. The day included historically themed activities, live music, antique vehicles from the Police and Fire Departments, and re-enactors and living history demonstrations. It also included the Lord and Lady Fairfax Awards Program, talks on topics in the Courthouse, Virginia's WWI/WWII Anniversary Mobile, Historic Courthouse Tours, a Revolutionary War memorial plaque dedication ceremony, petting zoo, and more.
The special guests who came all the way from England were Nicholas Fairfax, the 14th Lord Fairfax of Cameron, and his wife Annabel. Nicholas is the direct descendant of Thomas Fairfax, the sixth Lord Fairfax of Cameron, from whom the county gets its name.
