Guy Johnson rebuilt it in stone in 1773, and wings were added in the mid-nineteenth century.","why_significant":"The nomination presents Guy Park as an important example of Georgian architecture in the Mohawk Valley and as the home of Guy Johnson, Superintendent of Indian Affairs and a figure in colonial New York. Its later owner James Stewart links it to the Erie Canal, and the adjacent railroad tracks and Barge Canal Lock #11 tie it to nineteenth and twentieth century transportation and engineering.","narrative":"Guy Park is a two-story stone mansion on the Mohawk River at the west end of Amsterdam, New York. Guy Johnson built it in 1773, after lightning destroyed an earlier frame house put up in 1766 by Sir William Johnson for his daughter and her husband. Johnson, a Tory, served as Superintendent of Indian Affairs and fled to Canada in 1775; the property was later confiscated and sold. In the 1840s it passed to James Stewart, a Scottish stonecutter and contractor who worked on the Erie Canal, and the flanking wings were added in the mid-nineteenth century. The house now sits between railroad tracks and Barge Canal Lock #11, built after the state acquired the land in 1905. The Barge Canal was completed in 1918. Its coursed rubble masonry, Georgian symmetry and bracketed cornice mark the building, while the site reflects the shift from colonial Indian affairs to canal and rail transportation in the Mohawk Valley.","period_of_significance":"1773, 1850's, 1905-18","architect_builder":"Guy Johnson (builder); mid-nineteenth century enlargement by James Stewart","architectural_style":"Late Georgian","criteria":[],"status_note":"Condition listed as good and altered; owned by the State of New York, occupied, and opened as a historic site by the city of Amsterdam.
