Ohio is home to the largest ancient geometric earthworks in the world. Created 2,000 years ago, these monumental precincts were built as social architecture elegantly aligned with the movement of celestial bodies. Thousands of people gathered at these sites, using staggering quantities of materials along with strikingly uniform geometric principles to create ceremonial masterpieces. Today these sites hold a world waiting to be rediscovered.
The Great Circle Alliance (GCA) is an independent nonprofit organization with the goal of raising awareness and encouraging contemporary Native voices – artists, scholars, archeologists, and local communities – bringing human presence back into what was once a vibrant sophisticated culture. We operate an informal alliance with Native Americans connected to the sites, the OSU Newark Earthworks Center, the Ohio History Connection, Denison University, The Works! Museum, and Explore Licking County.
