The Indiana Medical History Museum is an Indiana monument to the beginning of psychiatric medical research. It is located on the grounds of what was formerly Central Indiana Hospital for the Insane. It was placed on the National Register of Historic Places on April 25, 1972, as the Old Pathology Building. It is the United States' oldest surviving pathology laboratory. The Museum is a not-for-profit organization that collects various relics, with over 15,000 by 1994, all related to medical history rather than just pathological items. A gallery to show rotating themes opened in 1990. The movie Eight Men Out filmed scenes in the library.
