It was the retirement home of railroad executive William Morrill Wadley, president of the Central Railroad from 1866 to 1882. The main house records the growth from a plantation plain structure to a larger Victorian house with Italianate influence, and the well-preserved outbuildings add to its integrity.","narrative":"Great Hill Place, also called Colaparchee, is a plantation complex near Bolingbroke in Monroe County, Georgia. Its main house began as an early 19th-century plantation plain dwelling. In 1873 railroad executive William Morrill Wadley bought the property for his retirement, and in 1874 he had the house enlarged and Victorianized, with a raised roof, a rear portion and a side wing. The result is a two-story, five-bay, weatherboarded, ell-shaped house with a bracketed central porch and Federal mantels preserved in the older rooms. Surrounding it are a brick smokehouse, a five-hole privy, a brick water tower, a dairy and vault house, a power house, an early frame cottage, barns, boxwood gardens, a pecan-lined lane and two cemeteries. The complex is regarded as one of Georgia's few nearly intact 19th-century plantations, reflecting Wadley's railroad career and the evolution of the house. It remained a working cattle farm, with growth along nearby highways posing a threat.","period_of_significance":"1874-75 (19th Century)","architect_builder":null,"architectural_style":"Plantation plain house enlarged in Victorian style with Italianate influence","criteria":[],"status_note":"Described as in good condition, altered, on its original site, and an operating cattle farm held in trust by a bank for an estate.
