Great Circle Earthworks

The Great Circle Earthworks, formerly known as Moundbuilders State Memorial, was built by the Hopewell culture approximately 2000 years ago. The circle is nearly 1200 feet in diameter and was used as a vast ceremonial center by its builders.

The Great Circle is one part of the Newark Earthworks State Memorial, the largest system of connected geometric earthworks built anywhere in the world. Octagon Earthworks and Wright Earthworks are both additional local sites that preserve other features of this majestic remnant of prehistoric Ohio.
