A large Muscogee (Creek) town, one of several known to have existed near the Fall Line area of the Ocmulgee River, arose amid the ancient Early Mississippian mounds on the Macon Plateau.  Englishmen from Charleston, eager to do business with the Creeks, constructed a Trading Post at Ocmulgee around 1690.  They swapped firearms, cloth, metal pots, tools and glass beads for deerskins and furs.  The stockade wall of the trading post is outlined by concrete "bumpers."
