Begin your visit at the primary museum of American Indian history at Fort Ancient, operated by the Ohio History Connection. Here, you can choose between visiting the grounds only or experiencing both the grounds and museum. The museum offers staff assistance, restrooms, a gift shop, and extensive exhibits that delve into the history of Indigenous cultures in the region and showcase the site’s features and archaeology. Don’t miss the orientation film that provides an introduction to the site. The shop has a variety of books, media, themed objects, and the World Heritage themed Guide to the Hopewell Ceremonial Earthworks.
Fort Ancient also offers an extensive outdoor experience that includes 2.5 miles of walking trails, a picnic area, and two overlooks that are accessible via a short walk from the parking lots at the south end of the site.
