Wave Hill is a estate in the Hudson Hill section of Riverdale in the Bronx, New York City. Wave Hill currently consists of public horticultural gardens and a cultural center, all situated on the slopes overlooking the Hudson River, with expansive views across the river to the New Jersey Palisades. The estate includes two houses and a botanical garden. The oldest part of the main house, Wave Hill House, dates back to 1843; Glyndor House dates from 1927 and contains a multi-room art gallery. Perkins Visitor Center, which was originally a garage, contains a gift shop and an information desk. During the late 19th century and early 20th century, numerous highly notable people resided in Wave Hill, either because they owned it, leased it, or stayed there as guests. In 1960, the estate was given to the City of New York, and Wave Hill is now a cultural center as well as a garden. In addition to visual arts exhibits, paid-ticket concert series take place on some Sunday afternoons in Armor Hall. Wave Hill is listed on the National Register of Historic Places and is a New York City designated landmark. History The original Wave Hill House was a gray fieldstone mansion built in 1843 by lawyer William Lewis Morris. It was owned from 1866 to 1903 by publisher William Henry Appleton, who enlarged the house in between 1866 and 1869 and again in 1890, and added greenhouses and gardens to the grounds. During these years, the house was visited by Thomas Henry Huxley, who helped Charles Darwin bring evolution by natural selection to the public's attention. Theodore Roosevelt's family rented Wave Hill during the summers of 1870 and 1871, and Mark Twain leased it from 1901 to 1903. The house was purchased in 1903 by George Walbridge Perkins, a partner of J. P. Morgan, along with adjacent property, including Glyndor, a house built by the Harriman family in 1888, which later burned down and was rebuilt in 1927. In 1910, Perkins added an underground building for recreation which included a bowling alley. Perkins performed extensive landscaping on the site and leased Wave Hill House to an eminent ichthyologist, Bashford Dean of the American Museum of Natural History, who built a stone addition to the building as a private museum, Armor Hall. Other famous residents of the estate included the conductor Arturo Toscanini (1942–1945) and chief members of the British
