What is the history of Newark, Ohio?
During the prehistoric period, Newark was an important center of cultural activity. From 100 BC to 500 AD the Newark area was transformed by the Hopewell culture. They built many earthen mounds, creating the single, largest earthwork complex in the Ohio River Valley. The earthworks covered several square miles. Observatory Mound, Observatory Circle, and the interconnected Octagon span nearly 3,000 feet in length. The Octagon alone is large enough to contain four Roman Colesiums. The Great Pyramid fits inside Observatory Circle precisely. The even larger 1180-foot-wide Newark Great Circle is the largest circular earthwork in the Americas, at least in construction effort. The 8 feet high walls surround a 5 feet deep moat, except at the entrance where the dimensions are even greater and more impressive. Archaeogeodesy and archaeoastronomy research has demonstrated advanced scientific understandings by the prehistoric cultures in the area by analyzing the placements, alignments, dimensions
