Fairfield State Hospital

Fairfield Hospital was created due to overcrowding at other hospitals. The hospital had 23 buildings that were connected by tunnels on 100 acres. The grounds included a chapel, theater, gym, bowling, library, power plant, lab, morgue, dairy farm, bakery, patient housing, staff dormitories, doctor housing, medical hospital, and cafeterias.  The hospital was opened in 1933 and had 500 patients, and 3 doctors. By the 1960's the hospital had 4,000 patients, 20 doctors and 50 nurses. The treatments included hydrotherapy, insulin shock therapy, patient seclusion, Electroconvulsive therapy and lobotomies. Many say Fairfield is haunted due to questionable deaths and patient abuse. The first questionable death was when one patient was beaten to death by the staff at Fairfield. Some patients also starved to death, because no staff had come to assist them with eating. It was closed in 1995.
