Ellis Mounds

Ellis Mounds is an archaeological site featuring multiple earthen mounds constructed for burial and ceremonial purposes on elevated terrain near the Great Miami River. The structures display layered construction from different periods, with evidence of successive building phases visible in their composition.

The site originated over 3000 years ago with evidence of occupation by successive cultures from the Adena through the Mississippian period. Multiple construction phases document how different societies modified and reused the mounds across centuries.

The mounds reflect how Native American communities marked their territories and honored their ancestors through earth construction. Visitors can observe how these elevated structures continue to define the landscape and connect to the people who built them.

Access to the site is available for research and educational visits under supervision. Sturdy footwear is recommended since the elevated terrain has steep slopes and uneven paths.

Archaeological studies reveal that the mounds once had stone-covered exteriors, as evidenced by overlapping stone formations still visible today. This detail shows the careful building methods used by ancient builders that visitors often miss.
