Old Castle Hall became the first building on the campus of Baker University in 1858. Old Castle was used for classes until 1871 and later served as a mill and then a dormitory. The building was restored in the 1950s, added to the National Register in 1971, and today serves as a museum.
Baker became the first college in Kansas. It is also notable for its practice of admitting female students. In fact, its first graduating class was 1/3rd female (it contained two men and one woman). Abraham Lincoln reportedly donated money to the college-the only such donation the former President made.
