The brick Gothic Revival and Italianate villa was built in 1850 and is surrounded by farm outbuildings and a designed landscape.","why_significant":"The nomination argues that Maple Grove is an outstanding example of a mid-19th century Hudson River valley country house, designed by a skilled but unidentified architect or architect-builder. It blends Gothic Revival and Italianate elements, and its estate plan includes an entrance drive lined with maples, river vistas and harmonious outbuildings. It was remodeled in 1891 by Wm. R. Walker & Son and is one of several estates along the South Road corridor.","narrative":"Maple Grove is a brick country house and farm estate built in 1850 on a 35-acre tract along South Road (U.S. 9) in the Town of Poughkeepsie. The main house combines Gothic Revival and Italianate details, including a bracketed cornice, carved sandstone drip-mold lintels, circular windows and a Gothic-ornamented front porch. It sits at the top of a long dirt drive lined with maple trees, with farmhouses, barns, a carriage barn and sandstone gateposts nearby. Charles A. Macy, a New York banker, developed the estate, and the Adolphus Hamilton family owned it from 1870 until the 1980s. In 1891 the interior was remodeled in Colonial Revival style by the Providence firm Wm. R. Walker & Son. The original designer is unknown. The property is significant for architecture and as a surviving example of the country estates created along this road. A fire in 1985 and later neglect damaged the house, which is now vacant, but most original and 1891 features remain.","period_of_significance":"1850 - 1891","architect_builder":"1891 remodeling: Wm.
