Ohio's Fascinating Indian Mounds

The State of Ohio has more than 70 Indian mounds, burial sites of the Adena and Hopewell tribes--the "mound builders"--who inhabited central and southern Ohio from roughly 3,000 BCE until the 16th century.

Many of these sites are open to the public, including the dramatic and fascinating Serpent Mound. Some even have museums and visitors centers accompanying them. Visiting Ohio's Indian mounds makes an interesting and educational weekend side trip from Cleveland

The Serpent Mound is the most dramatic of the Ohio Indian Mounds. It is also the largest effigy earthwork in the world. Located in Adams County in Southern Ohio near the Ohio River, the 1,370-foot long site is shaped like a curved snake with its mouth open and an egg at its mouth. The site, believed to be built by the Adena people, was discovered by Chillicothe surveyors, Ephraim Squier and Edwin Davis in 1846.

Today, the site is administered by the Ohio Historical Society and includes a museum about the Adena people. The site is open year round. The museum is open from March through December. Hours vary by season. Admission is free.
