The hospital was built in the early 1940s, believed to be a Works Progress Administration-funded project.

The War Department completed its construction for use as a psychiatric facility for battle-traumatized soldiers.

[1][2] When the war ended, the hospital was transferred back to New York State, where it essentially operated as the tubercular division of Pilgrim for a few years.

Activities include hiking, biking, dog training, and model airplane flying.
