Masterpieces of human creative genius, the Hopewell Ceremonial Earthworks are gigantic earthen enclosures built by American Indians 2,000 years ago.

They were places of ceremony connected to the cosmos by alignments to key risings and settings of the moon and sun. Come and experience these sacred earthworks of the ancient Hopewell culture and gain a new appreciation of the achievements of Ohio’s Indigenous peoples—as well as a deeper connection to the world and our place in it.

The UNESCO World Heritage committee has inscribed the Hopewell Ceremonial Earthworks recognizing its significance in humanity's achievements, and includes:

The Hopewell Ceremonial Earthworks are complex masterpieces of landscape architecture. The huge squares, circles, and octagons, which are geometrically precise and align perfectly with the cycles of the sun and moon, were built by dispersed communities of American Indians who periodically gathered at these special places to worship and stay connected to one another. The earthworks are incredibly big to accommodate those large numbers of people.

Artifacts found at these sites are made from unusual raw materials such as mica from Appalachia, seashells from the Gulf of Mexico, and obsidian from the Rocky Mountains. This shows that people traveled here from the ends of the Hopewell world bringing with them rare and precious gifts. The immense effort this would have required further solidifies these earthworks as centers of human ingenuity.
