The Springfield area has several historic attractions. Pennsylvania House, a tavern built in the 1820's and later a stagecoach stop on the Cumberland Road, is now a museum. The George Rogers Clark Memorial, in a nearby state park, commemorates a battle with Shawnee Indians in 1780. The city is the home of Wittenberg University, founded 1845.
James Demint settled here in 1799 and laid out the town in 1801. After 1830 improved transportation, including the Cumberland Road and a railway, stimulated growth, and the city was incorporated in 1850.
