Haymarket, in northwest Prince William County, owes its location to an abandoned Indian hunting path which became Old Carolina Road. It was used by settlers as a route from Pennsylvania to the Carolinas. Haymarket grew around the intersection of Carolina and Dumfries Roads. Almost all of the town was burned by Union troops in 1862. Only St. Paul's Church and three small houses nearby were spared. As late as 1975, horse-drawn wagons could sometimes be seen in Haymarket, but since the completion of Interstate 66 nearby in the later 1970s, nearly all trace of Haymarket's rural past has disappeared. What remains of the old downtown has been replaced by professional offices, residential and commercial development, and widened commuter thoroughfares.
