The Wright Earthworks are remnants of the Newark Earthworks, the largest set of geometric earthworks built by the Hopewell culture (100 B.C. to A.D. 500). Located in central Licking County, the Wright Earthworks consist of a fragment of a geometrically near-perfect square enclosure and part of one wall that originally formed a set of parallel embankments, which led from the square to a large oval enclosure.
The sides of the Newark square originally ranged in length from about 940 to 950 feet and they enclosed about 20 acres. The remaining segment of one wall of the square is less than two hundred feet long.
Farming and construction associated with building the Ohio Canal and the streets and houses of the city of Newark destroyed much of the square enclosure and its associated mounds. The Wright Earthworks are named in honor of Mrs. Frances Rees Wright who donated the site to the Ohio Historical Society in 1934.
The surviving parts of the Newark Earthworks are recognized as a National Historic Landmark. In 2006, the State of Ohio designated the Newark Earthworks as "the official prehistoric monument of the state."
