The Stuart-Mosby Civil War Cavalry Museum opened on Centreville Day 2011. It is run solely by volunteers and displays artifacts connected to Confederate stalwarts Gen. James Ewell Brown "Jeb" Stuart, who first distinguished himself at the battle of First Manassas in July 1861, and Col. John Mosby, whose wartime feats remain legendary among historians and in Fairfax County.
The museum is located in the Centreville Historic District and is currently open on Saturdays and Mondays from 10 a.m. to 4 p.m. It is free and open to the public.
