I "discovered" this site when I lived in Kalamazoo during the mid-1990s. I was intrigued because it was a abandoned modern-style institutional building situated in the middle of an older residential neighborhood.
The building opened in 1954 as a Tuberculosis Sanatorium. It was turned into a Mental Health facility in 1970, and eventually closed in the late 1980's. Despite several potential plans for reuse, nothing has yet happened with this building.
