The Lima Tuberculosis Hospital was a tuberculosis sanatorium built in 1911 to deal with the leading causes of death in the United States in the early twentieth century. It held 24 beds originally, and was remodeled in 1927 to hold 158 beds. The hospital was renamed Ottawa Valley Hospital in 1960. By 1970 it was nearly empty, and it closed its doors in 1973. It is rumored to be haunted, but one adventurer attributes the noises to the nearby Lima Refinery.
