New Philadelphia National Historic Site

National Historic Site · Illinois · National Park Service

To a casual observer, New Philadelphia looked like a typical Illinois pioneer town. But a closer look revealed a unique and racially diverse community. New Philadelphia was the first US town platted and registered by an African American. A formerly enslaved man, Free Frank McWorter, founded New Philadelphia in 1836 and purchased freedom for himself and 15 family members.
