World Heritage

The Great Circle Earthworks

Photo of Mound 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.

Summer 2012 Events Related to the Ancient Ohio Trail

The Ancient Ohio Trail ( is a massive website designed to educate the public about Ohio earthworks, lead travelers around the state to visit 55 sites, and provide layer upon layer of easily useable interpretive materials. All this online material is in files which are downloadable onto computers, laptops, iPhones and iPads. The Ancient Ohio Trail has been created by CERHAS (the Center for the Electronic Reconstruction of Historical and Archaeological Sites) at the University of Cincinnati in partnership with the Newark Earthworks Center at The Ohio State University. The project is funded by an Interpreting America’s Historical Places grant from the National Endowment for the Humanities.

The Ancient Ohio Summer includes multiple public events planned to enrich the traveler’s experience and supplement the digital interpretive materials about earthworks. The first of these on May 5 will precede the May 20 publication date. All events are free of charge unless otherwise noted below.
