The Great Serpent Mound is a 1,348-foot-long, three-foot-high prehistoric effigy mound on a plateau of the Serpent Mound crater along Ohio Brush Creek in Adams County, Ohio.
Researchers have at different times attributed construction of the mound to two different prehistoric indigenous cultures. Originally thought to be Adena in origin, scholars now believe the mound was built by members of the Fort Ancient culture around 1070 CE. More recent research places the mound’s construction at around 300 BCE, once again suggesting Adena construction. Serpent Mound is the largest serpent effigy in the world.
There’s a great little museum about the Indigenous culture and Mound artifacts and history.
