Explore North America’s largest ancient hilltop enclosure, built 2,000 years ago. A National Historic Landmark, the site is thought to have served as a social and ceremonial gathering place. Experience an on-site museum, recreated American Indian garden and three miles of hiking trails with scenic overlooks. Average visit time: Allow 2+ hours
 

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. 

Fort Ancient Earthworks & Nature Preserve is managed locally by the Dayton Society of Natural History.

 

World Heritage

Fort Ancient is on the Tentative List for World Heritage. The site is one of seven Ohio sites in a serial nomination of Hopewell Ceremonial Earthworks. In addition to Fort Ancient, the sites are Newark Earthworks and five sites that make up Hopewell Culture National Historical Park in Chillicothe. For more information on World Heritage and how you can help, visit http://worldheritageohio.org .

The Ohio History Connection is currently conducting research and seeking input regarding issues, concerns and management options to assist in the creation of a Historic Site Management Plan which will be a guiding document for the future protection and management of Fort Ancient.  As part of the process, representatives of the Ohio History Connection and others will be soliciting input and answering questions at upcoming Warren County township trustee meetings, including:

  • Washington Township: held August 24, 2015
  • Salem Township: September 8, 2015 at 7 p.m.
  • Turtlecreek Township: September 14, 2015 at 7 p.m.
  • Harlan Township: October 7, 2015 at 7 p.m.
A public meeting will be held at Fort Ancient Earthworks and Nature Preserve in the fall-winter of 2015-16.  Please revisit this website for the announcement of the meeting date and time.

If you have any questions or concerns regarding the Fort Ancient Historic Site Management Plan, please contact the Ohio History Connection's Regional Site Coordinator, Erin Bartlett at ebartlett@ohiohistory.org.
