A thousand years before the first bricks were laid at Machu Picchu, Indigenous people in what is now southern Ohio were building monumental earthworks with astonishing geometric precision. These sacred spaces—vast circles, squares, and octagons sculpted from earth—still stand today, quietly nestled in the rolling landscape of Ross County. If you’ve never heard of the Hopewell Culture, you’re not alone. But once you walk among their ceremonial mounds, it’s hard to forget.
Hopewell Culture National Historical Park, located just outside Chillicothe, Ohio, preserves the remnants of this ancient civilization. Recognized as a UNESCO World Heritage Site in 2023, the park offers a rare glimpse into a complex society that thrived between 200 BCE and 500 CE. Their legacy isn’t just in the mounds—they left behind a story of spiritual depth, astronomical knowledge, and continent-spanning trade networks.
What to See & Do
The park is composed of four publicly accessible sites, each offering a unique perspective on Hopewellian life and culture.
Mound City Group
This is the heart of the park and home to the visitor center. It features 23 reconstructed burial mounds, each originally built over the remains of ceremonial structures. Artifacts such as copper figures, mica, and intricately carved pipes were discovered here, indicating the site’s significance as a ceremonial center. The visitor center offers a 20-minute orientation film and exhibits that provide context to the mounds and the people who built them.
Hopewell Mound Group
Located a short drive from Mound City, this site contains the largest known Hopewell mound, Mound 25, and an earthen enclosure spanning 116 acres. The scale of this site suggests it was a major ceremonial center, possibly hosting gatherings of people from across the region.
Seip Earthworks
Situated along U.S. Route 50, Seip Earthworks features a large central mound and remnants of geometric earthworks. The site’s layout indicates it was used for ceremonial purposes, and ongoing research continues to uncover its mysteries.
Hopeton Earthworks
Directly across the Scioto River from Mound City, Hopeton Earthworks boasts large geometric earthworks, including circles and squares. While the mounds here are less prominent, the site’s precise layout and scale are impressive.
