Come visit Fort Ancient in Oregonia, Ohio to celebrate its designation as a UNESCO World Heritage Site!

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.

The site is one of eight Ohio sites in a serial nomination of Hopewell Ceremonial Earthworks. In addition to Fort Ancient, the sites are Newark Earthworks and the six sites that make up Hopewell Culture National Historical Park in Chillicothe.

Fort Ancient Earthworks & Nature Preserve is managed by the Ohio History Connection.
