Atlas is a rural property of about 8.17 acres near Haymarket and the settlement of Waterfall in northwest Prince William County, Virginia. It centers on a two-and-one-half-story frame Georgian house built in 1795, with a smokehouse, barn ruins and a grave.","why_significant":"The nomination calls the house one of the finest and least altered examples of late Georgian domestic architecture in Prince William County. Its parlor mantel and overmantel are finely carved, and the overmantel holds a circa 1830-1840 folk portrait, Maiden in Prayer, described as unique in the county as interior architectural decoration. The house is also valued for its high degree of interior integrity despite deterioration.","narrative":"Mt. Atlas is a rural property of about eight acres near Waterfall, north of Haymarket in Prince William County. Its main building is a three-bay, side-hall, frame Georgian house built in 1795 by Peter Whiting and sold in 1801 to Charles B. Carter. The land was once part of Robert \"King\" Carter's Bull Run Tract. The house keeps its molded boxed cornice with modillions, original flooring, six-panel doors and much early plaster. Its best-known feature is the parlor's carved classical mantel and overmantel, which holds a folk portrait titled Maiden in Prayer, painted around 1830-1840 by an itinerant artist. Later changes include a rear ell, dormers and a front porch added in the early twentieth century. A smokehouse, barn ruins and Carter's grave are also part of the property. The house has stood vacant and deteriorating since structural problems led the owners to build a new residence in 1974, yet its interiors remain largely intact.","period_of_significance":"1790-1800, 1870-1910","architect_builder":"Peter B.
