Changes in the treatment of mental illness, such as psychotherapy and psychotropic drugs, were making large-scale facilities relics and allowing more patients to lead more normal lives without being committed. A major fire destroyed a hospital wing in the 1960s and threatened to spread to the administration building, but was halted in a connecting hallway. The section was rebuilt, although some large roof beams still showed evidence of the earlier fire. Though 1971 saw the addition of the Snow Recreational center, by the late 1970s the hospital administration had decided to shut down the two main wings as few patients were residing in them and due to neglect some of the floors had collapsed. The hospital housed 1,780 patients by 1976. The state offices of Mental Health and Historic Preservation clashed over a plan to demolish the wings, even after the National Historic Landmark designation in 1989.
