The mounds in Newark, Ohio, part of the Newark Earthworks, were constructed by ancient Native American cultures, primarily the Adena and later the Hopewell, between approximately 100 B.C. and 500 A.D. These earthworks are among the largest and most complex in North America, showcasing significant advancements in engineering and ceremonial practices of the time. The Newark Earthworks included a series of mounds and geometric earthworks, serving both ceremonial and astronomical purposes.
