Gilman, Jr. estate in the hamlet of Palisades, Orangetown, Rockland County, New York. It sits on about 14 acres above the Hudson River and includes a brick High Victorian Gothic main house built 1872-74, plus outbuildings and landscape features.","why_significant":"The estate is presented as an excellent example of a late nineteenth century High Victorian Gothic estate, designed by the locally prominent Winthrop S. Gilman, Jr. It also marks the transition in Palisades from informal early summer houses to the more opulent, formal estates of the early twentieth century. Surviving service buildings and an intact setting add to its value.","narrative":"Neiderhurst is a 14-acre Hudson River estate in Palisades, Rockland County, New York, created by banker and amateur architect Winthrop S. Gilman, Jr. Its brick main house, built between 1872 and 1874 as a summer retreat, shows High Victorian Gothic design through checkered polychrome brickwork, tile insets, steep gabled roofs, jerkin-headed dormers and tall chimneys. Earlier Gothic Revival buildings stand nearby: Fern Lodge, begun in 1866, a barn from 1872, and a circular 1869 observatory built for Gilman's telescope, later converted to a cote. A winding drive, mature trees including copper beeches, a concrete pergola and a fieldstone-walled garden room complete the grounds. The estate matters because it shows Palisades changing from a river port hamlet into a country retreat for wealthy New Yorkers, and it represents a middle stage between informal early country houses and the grand formal estates that followed. The setting remains largely unaltered.","period_of_significance":"1866 to circa 1935","architect_builder":"Architect: Winthrop S.
