The Ocmulgee Mounds

Ocmulgee Mounds National Historical Park, in present-day Macon, Georgia, has evidence of 17,000 years of continuous human habitation. Its chief remains are major earthworks built before 1000 CE by the South Appalachian Mississippian culture. These include the Great Temple and other ceremonial mounds, a burial mound, and defensive trenches. They represented highly skilled engineering techniques and soil knowledge, and the organization of many laborers. The 702-acre park is located on the east bank of the Ocmulgee River.
