The Kings Park Psychiatric Hospital was established in 1885 and began its life as a farm colony. The hospital was known as the Kings County Asylum due to that area being part of Kings County NY at that time. In 1895, the State of New York would take control of the property to attempt to alleviate the issue of overcrowding at the farm colony. The name was officially changed to Kings Park State Hospital.

At the time the institution was named the Kings Park State Hospital, the community in which it was located was called Indian Head, NY. The hospital became so large within the community, the town eventually adopted the name Kings Park and is still known as such today. The hospital began to grow through the 1900's to a tremendous size. It would eventually grow to well over 500 acres with over 100 buildings on campus.

In the late 1930's, the most iconic building on campus would be constructed. This building was known as building 93, a 13 story high-rise building funded by WPA money. By the time of deinstitutionalization, only the first few floors were in use. The patient population was significantly decreasing through the years and the decision was made to close Kings Park in 1996. The campus of over 100 buildings that once held 9,303 patients suddenly fell silent.
