The Highbanks Park Earthworks consist of a C-shaped embankment that encloses a tall bluff overlooking the Olentangy River in Delaware County, Ohio. The earthen walls are about 3 feet high and are broken by three openings, or gateways. There is a ditch on the exterior of the wall that originally was 3 feet deep, indicating the ditch was the source of the earth that formed the wall. This embankment and ditch may have served as a defensive wall for a Late Woodland (600 A.D. to 1200 A.D.) or Late Prehistoric (900 A.D. to 1650 A.D.) village of prehistoric Native American people.
A large Late Woodland village, the DECCO site, is located on the opposite bank of the Olentangy River. The residents of the DECCO site may have used the Highbanks Earthwork in times of trouble.
The Highbanks Earthwork is preserved in a City of Columbus Metro Park located three-and-a-half miles north of the I-270/I-71 interchange on the north side of Columbus. There also are two Adena culture (800 B.C. to 1 A.D.) conical mounds at the Highbanks Metro Park. The Highbanks Park Earthworks are listed on the National Register of Historic Places.
The Highbanks Earthworks occasionally are confused with High Bank Earthworks of the Hopewell people in Ross County, Ohio.
