The Central Islip Psychiatric Center was a psychiatric hospital in Central Islip, New York, USA from 1889 until 1996.The center was one of the four major hospital "farms" in central Long Island to house the sick from New York City; the others were Kings Park, Pilgrim State Hospital, and Edgewood State Hospital. In 1955 it housed 10,000 patients, making it the USA's second biggest psychiatric hospital to Pilgrim State Hospital, which was the largest psychiatric institution ever to exist in the United States.HistoryIt opened in 1889 to house the sick from Manhattan in what was called at the time the New Colony. Kings County Farm Colony opened in the fall of 1886 to house those from Brooklyn. Pilgrim opened in 1931 and Edgewood in 1946 (which acted as Pilgrim's Tubercular Division).The state bought the land for US$25 per acre.49 male and 40 female patients were admitted in 1889 for "O&O" (Occupation and Oxygen) and "R&R" (Rest and Relaxation) at a working farm. Patients cleared the land, constructed buildings, made the furniture and mattresses, sewed their clothing, grew crops and raised dairy cattle, pigs and chickens.After New York State bought it, it was renamed the Manhattan State Hospital for the Insane (although the "for Insane" portion was frequently not included in articles).
