WASHINGTON — Secretary of the Interior Deb Haaland today applauded the decision by the UNESCO World Heritage Committee to include on the World Heritage List Hopewell Ceremonial Earthworks, a group of eight ancient earthwork sites in southern Ohio. The World Heritage Committee made the decision to inscribe Hopewell Ceremonial Earthworks on the highly selective World Heritage List by consensus at its 45th session in Riyadh, Saudi Arabia on September 19, 2023. Five of the earthwork sites are managed by the National Park Service and three are managed by the Ohio History Connection.

“Today’s designation by UNESCO is a tremendous opportunity and recognition of the contributions of America’s Indigenous Peoples,” said Secretary Deb Haaland. “World Heritage designation is an opportunity for the United States to share the whole story of America and the remarkable diversity of our cultural heritage as well as the beauty of our land. The Hopewell Ceremonial Earthworks are unique creations of America’s indigenous people and a remarkable survival of our ancient history.”

“The inscription of Hopewell Ceremonial Earthworks to the World Heritage List is the capstone to years of hard work by many partners. This accomplishment is an invitation for the world to discover this remarkable cultural and historical treasure,” said Assistant Secretary for Fish and Wildlife and Parks Shannon Estenoz, who serves as chair for the Federal Interagency Panel for World Heritage. “World Heritage Sites draw visitors from around the world, providing both recognition to local communities and a boost to their economies. We encourage visitors to journey into the past and experience first-hand the creative genius of the Hopewell people.”

The sites that comprise Hopewell Ceremonial Earthworks were built between 1,500 and 2,200 years ago by people now referred to as the Hopewell Culture. The earthworks, built on an enormous scale and using a standard unit of measure, form precise squares, circles, and octagons as well as a hilltop sculpted to enclose a vast plaza. The geometric forms are consistently deployed across great distances and encode alignments with both the sun’s cycles and the far more complex patterns of the moon. Artifacts, which are among the most outstanding art objects produced in pre-Columbian North America, show that those who built the earthworks interacted with people as far away as the Yellowstone basin and Florida. These are among the largest earthworks in the world that are not fortifications or defensive structures.

The properties comprising the Hopewell Ceremonial Earthworks:

• Hopewell Culture National Historical Park in Chillicothe, including the Mound City Group, Hopewell Mound Group, Seip Earthworks, High Bank Earthworks and Hopeton Earthworks
• The Ohio History Connection’s Octagon Earthworks and Great Circle Earthworks in Newark and Fort Ancient Earthworks in Oregonia

During a recent vote, the World Heritage Committee members agreed that these earthworks deserve to be recognized alongside such places as Stonehenge in England and the Nazca Lines in Peru, as well as other iconic places in the United States, including Independence Hall and the Grand Canyon. The National Park Service manages all or part of 19 of the 25 World Heritage Sites in the United States. It is also the principal U.S. government agency responsible for implementing the World Heritage Convention in cooperation with the Department of State.

The inclusion of a site in the World Heritage List does not affect U.S. sovereignty or management of the sites, which remain subject only to U.S., state and local laws. Detailed information on the World Heritage Program and the process for the selection of U.S. sites can be found at the National Park Service’s website.
