Great Circle Earthworks
Heath, OH
A 365 m circular earthen enclosure built by the Hopewell culture about 2,000 years ago, part of the Hopewell Ceremonial Earthworks World Heritage Site. Free museum and park.
The Great Circle Earthworks are a circular earthwork of the Hopewell culture in Heath near Newark, Ohio, and part of the UNESCO World Heritage Site Hopewell Ceremonial Earthworks. The circle has a diameter of almost 1,200 feet (365 m) and encloses just under 30 acres (12 hectares). The walls are 8 to 13 feet (2.4 to 4 m) high, with an interior ditch of similar depth. An opening about 200 feet (60 m) wide breaks the circle.
At the center lies the Eagle Mound, named for its symmetrical, slightly winged shape. The site is about 2,000 years old, and only a small part of it has been investigated archaeologically. The Ohio History Connection museum stands outside the entrance, and the earthworks themselves are open from dawn to dusk. The museum is open Wednesday to Sunday with free admission (as of October 2026, check in advance). Address: 455 Hebron Road, Heath.
