Towering Façade of Building 93 at Kings Park Psychiatric Center

Building 93 is the tallest structure at the former Kings Park Psychiatric Center on Long Island, rising thirteen stories above the surrounding campus. New York State opened the facility in 1885 as the Kings County Farm, later expanding it into one of the state's largest psychiatric hospitals, with a peak population of nearly 9,000 patients by the mid-20th century. Building 93 was completed in 1939 to house patients and support services as the hospital grew increasingly self-sufficient, operating its own power plant, farms, and rail spur. Deinstitutionalization and shifts in mental health policy led to the hospital's decline, and the state closed it in 1996. Much of the campus, including Building 93, has sat vacant since then, though a portion of the grounds was converted into Nissequogue River State Park in 2000.
