Round Hill is an unincorporated community in Frederick County, Virginia, USA.
 Round Hill is located west of Winchester on the Northwestern Turnpike (U.S. Route 50).
 It is often referred to as Round Hill after Round Hill (1381 ft) but this may cause confusion as there is already an incorporated town with the same name in nearby Loudoun County.
 Round Hill has also been known as Chambersville throughout its history.
 It lies on Round Hill Road (SR 803), off U.S. Route 50 at Poorhouse Road (SR 654).
Round Hill is a town in Loudoun County, Virginia, United States.

 The town is located at the crossroads of Virginia routes 7 and 719 (Woodgrove Road), approximately 50 miles northwest of Washington, D.C.
 It was named "Round Hill" for being located two miles northeast of a 910-foot hill used during the American Civil War as a signal post by both Confederate and Union troops.
The West Townshend Stone Arch Bridge carries Round Hill Road across Tannery Brook in the village of West Townshend, Vermont.

Mount Rose (formerly called Stout's Corner) is an unincorporated community located within Hopewell Township, in Mercer County, New Jersey, United States, situated at the corner of Carter Road (also called County Route 569 and Hopewell-Princeton Road), Pennington-Rocky Hill Road, and Cherry Valley Road.
 It is named for a local gardener.
 The Mount Rose section of Rocky Hill Ridge through the community also takes its name from the gardener.
 Richard Stout opened the first general store in the village around 1822 and in 1830, Josiah Cook and Reuben Savidge opened a second store.

 In its heyday the community had about 20 houses.
 Nathaniel Drake opened an applejack distillery in the village in the mid-19th century.
 He made and sold peach brandy, apple cider and apple whiskey.
 The Whiskey House (192 Pennington-Rocky Hill Road), the office building for the distillery and the only remaining Drake building in the village, is listed on the township, state and national registers of historic places.
 The community's schoolhouse, a stone building east of the crossroads, was later replaced by a frame building on the southern end of the village that is a private residence today.
 After 1880, Mount Rose began shrinking, due to the growth of nearby Hopewell.
 It is planned that the Lawrence Hopewell Trail will go through the community.
