It includes Wave Hill house (central section built 1843-44), the Georgian Revival mansion Glyndor II (1926-27), and outbuildings and gardens, and is now city-owned parkland.","why_significant":"The nomination argues that Wave Hill is the southernmost of the nineteenth-century Hudson River Valley estates and is tied to notable figures including William Lewis Morris, Theodore Roosevelt, Mark Twain and conservationist George W. Perkins. Its buildings and landscaping show an early nineteenth-century manor evolving into a turn-of-the-century estate and then a public park and environmental center. It also contains work by prominent architects and an early underground recreation building.","narrative":"Wave Hill is a 20-acre estate on the highlands of Riverdale in the Bronx, with sweeping views of the Hudson River and the Palisades. Its oldest part is a fieldstone Greek Revival house built in 1843-44 for William Lewis Morris, later enlarged and altered for publisher William Henry Appleton, then remodeled in the early 1930s in Georgian Revival style. Additions include a neo-Gothic armor hall of 1929 built for Dr. Bashford Dean. The grounds also hold Glyndor II, a brick Georgian Revival mansion of the 1920s, a 1909 recreation building built largely underground, greenhouses, gardens and a fieldstone perimeter wall. Residents and tenants over the years included Theodore Roosevelt's family, Mark Twain and Arturo Toscanini. Financier and conservationist George W. Perkins unified the estate in 1903 and shaped its landscaping. The property is significant for these associations and for its architecture and landscape, and it now operates as a city-owned park and environmental center.","period_of_significance":null,"architect_builder":"Babb, Cook & Willard; Oliver Perry Morton; Butler & Corse; also Dwight James Baum, Heins & LaFarge, Lord & Burnham, Robert M.
