Octagon Earthworks is part of the Newark Earthworks in central Ohio. It is unique, with a mysterious shape built with astonishing precision.

Octagon Earthworks is comprised of two geometric enclosures featuring a circle enclosing 20 acres and an octagon enclosing 50 acres. The walls of each enclosure reach eye level.
The Hopewell culture was responsible for creating the Newark Earthworks.
Octagon Earthworks is part of the Hopewell Ceremonial Earthworks, which is Ohio’s first UNESCO World Heritage site.
As there has been little investigative archaeological work carried out at Octagon Earthworks, historians and researchers have their beliefs about these mounds. Hopewell Ceremonial Earthworks are looking forward to having archaeological digs carried out in the future.

It is situated on a private golf course, so pay attention to the signs. You do have to walk right next to the main golf course building to get to the other side of the Earthworks. However, a court ruling and subsequent settlement between the golf course owners and Ohio History Connection means the site will be fully open to the public in the future.
