This 105-acre site is the most significant pre-historic site on the byway.  A viewing deck with interpretive signs overlooks the site. The mounds were constructed 700-1000 years ago by the Native Americans who were the first people to practice large scale agriculture in southern Illinois. The mounds were platforms on which the Chief and other elite leaders of this society lived or ruled from, and on which thatch-roofed homes, ceremonial buildings, and temples were constructed.  The site has been designated a National Historic Landmark and is on the National Register of Historic Places.

Open year round.
Reservations are advisable for large group tours.
