The Thornton-Williams House is a well-preserved central-hallway I-house, a relatively rare type in Georgia, with original materials and an elaborate balcony balustrade. The Swint-Hopkins House is a somewhat altered Georgian Cottage, and the stone-walled Thornton Cemetery and the Mullins Cemetery are good surviving examples of family cemetery design.","narrative":"Thornton Plantation is a rural farm complex about seven miles west of Pine Mountain in Harris County, Georgia. It includes two houses, two family cemeteries and surrounding fields. The older house, built around 1850, is a two-story Greek Revival I-house with a full-height porch on six tapered square piers, a balcony with a sheaf-of-wheat balustrade, and an elaborate entrance with sidelights and transom. Much original material survives, including doors, mantels, floors and ceilings. A quarter mile north stands a vernacular farmhouse from about 1890, a Georgian Cottage with a central hall that grew through additions over nearly a century. Between and beside them lie the stone-walled Thornton Cemetery and the wire-fenced Mullins Cemetery, with rock markers and marble obelisks. The property was listed for its architecture and landscape design, and as the surviving core of a once large family farm that operated through 1954. Nearby land is now being turned into residential subdivisions.","period_of_significance":"C. 1850-1954","architect_builder":null,"architectural_style":"Mid-19th Century/Greek Revival; Georgian Cottage type","criteria":["C"],"status_note":"Both houses are still used as single dwellings, and the cemeteries remain in place.
