First built in 1909, this became the largest municipal TB hospital in the U.S. in the first half of the 20th century. As fate would have it, the breakthroughs in research performed here led its ultimate demise as a Tuberculosis hospital as the number of cases dwindled to nothing. Although most of the old TB treatment buildings are abandoned, much of the campus serves as an old age home.
