The spacious Federal vernacular farmhouse at Rose Hill Farm was built in 1820 for Amos Denham, who operated the house as a tavern serving travelers along Ashby’s Gap Turnpike in Loudoun County. Thomas Glascock, a large landowner, purchased the farm in 1853 and made extensive improvements including adding a cast-iron veranda said to have been shipped from New Orleans. Glascock also built a large stone granary. During the Civil War, Confederate ranger Col. John S. Mosby was a frequent dinner guest at Rose Hill. The house served as an observation point by Confederate Gen. J. E. B Stuart in 1863. Union troops burned Glascock’s barns in 1864. Despite the Civil War action, Rose Hill preserves, in addition to the granary, a stone slave quarters now attached to the house, an octagonal icehouse, a three-story brick slave quarters, a stone granary, and an early stone bridge. Rose Hill remains a working farm, owned by Glascock descendants.
