Newark Earthworks

The Newark Earthworks are a complex of ancient Native American geometric earth mounds and earthworks located in Ohio, built around 1000 CE by the Adena and later Hopewell cultures. Covering approximately four miles, they include circular and square formations aligned with celestial events like solstices. These earthworks served ceremonial, astronomical, and possibly territorial purposes, reflecting advanced engineering and astronomical knowledge. Today, they are recognized as a UNESCO World Heritage Site, highlighting their cultural and historical significance as a testament to the ingenuity of prehistoric Native American societies.
