Fort Belvoir

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 once stood on land now on 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.

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.
