NEWARK, Ohio (AP) — Ohio’s historical society is one step away from gaining control of ancient ceremonial and burial earthworks maintained by a country club where members golf alongside the mounds.

A trial was slated to begin Tuesday to determine how much the historical society must pay for the site, which is among eight ancient areas in the Hopewell Earthworks system named a World Heritage Site last year.

Built between 2,000 and 1,600 years ago by people from the Hopewell Culture, the earthworks were host to ceremonies that drew people from across the continent, based on archeological discoveries of raw materials from as far west as the Rocky Mountains.

The Ohio History Connection, which owns the 2,000-year-old Octagon Earthworks in Newark in central Ohio, won a state Supreme Court decision a year and a half ago allowing it to reclaim a lease held by the Moundbuilders Country Club so that it can turn the site into a public park.
