The US Department of the Interior has nominated eight of Hopewell's earthworks for consideration in 2023 as a Unesco World Heritage site. These include The Great Circle and The Octagon in Newark, Ohio, as well Ohio's first state park, Fort Ancient (not an actual fort). The other five are part of the Hopewell Culture National Historical Park: Mound City, Hopeton Earthworks, High Bank Works, Hopewell Mound Group and Seip Earthworks.
