Ohio Earthworks

Ohio Earthworks refers to a series of ancient mounds and earth structures built by Native American cultures in the region now known as Ohio, particularly by the Adena and Hopewell peoples. These impressive earthworks, which include burial mounds, geometric shapes, and effigy mounds, were constructed between 1000 BCE and 500 CE. They served various purposes, such as burial sites, ceremonial centers, and social gathering spaces. Significant sites, like the Serpent Mound and the Newark Earthworks, showcase intricate designs and alignments with celestial events, reflecting the advanced understanding of geometry and astronomy by these indigenous cultures.
