| NEWARK EARTHWORKS NEWARK, OHIO The largest geometric earthworks are in Newark, Ohio. They were constructed by the Hopewell Culture and probably date from at least 250 A.D. The most significant sites are Great Circle Octagon Earthworks. My favorite explanation for these earthworks is that they were a model of sorts for the universe and the belief that they could have served as a portal for the spirits of their deceased to reach the next world. |
