History

Fort Ancient Earthworks & Nature Preserve is Ohio’s first state park. In April 1891, the state legislature authorized the Ohio Archaeological and Historical Society (now the Ohio History Connection) to care for the site. In 1966, Fort Ancient became nationally recognized when it was named a National Historic Landmark. Learn more here.
