Google Maps labels this area "Willard State Hospital".
By 1950, New York operated 30 state hospitals with more than 120,000 patients. Willard's census reached an all-time high of 4,076 in 1955, and conditions within the institutions were harsh. In the mid-1950s, state hospitals began to use newly developed antipsychotic drugs to control patients crammed into ever-tighter living quarters. In the early 1970s, political and economic factors including new laws that promoted patients' rights and forbade unpaid patient labor resulted in a shift away from long-term institutionalization. The facility was again renamed, becoming Willard Psychiatric Center. By 1974, Willard's census had declined to less than a thousand, and the patient population dwindled to a few hundred by the time the facility closed in 1995. More than 50,000 patients were admitted to Willard during its 126-year history, and nearly half of those died there.
