Columbus - Prehistoric Indian Mounds

Some of the most interesting of the prehistoric Indian mounds can be seen on a round trip from Columbus, starting on U.S. 23, going south. Among them are the 23 mounds (200 BC-AD 500) of the Mound City Group National Monument at Chillicothe; the single large mound (250 ft long, 30 ft high) in the Seip National Monument (17 mi. west of Chillicothe); the Serpent Mound State Memorial on SR 73 (total distance 90 mi.), a quarter-mile long mound in the form of a snake (800 BC to AD100), the largest of its kind; and the Fort Ancient State Memorial at Lebanon (total distance 138 mi.), a cult site constructed about 500 ad by Indians of the Hopewell Culture.
