Fort Ancient State Memorial

n Warren County, Ohio, an isolated peninsula rises 80 meters (about 260 feet) above the muddy banks of the Little Miami River. There exists an immense monument to the dedication and technological savvy of the original inhabitants of prehistoric North America. This vast 51 hectare (about 126 acres) plateau is enclosed by embankment walls that stand 1.5 to 7 meters (about 5 to 23 feet) high, constructed by repeatedly dumping baskets loaded with soil upon one another. The Hopewell, known for their engineering expertise, built these walls and many other features both within the enclosure and on the steep valleys that surround the site: conical and crescent-shaped mounds, limestone pavements and circles, and many subsurface elements that are currently coming to light. Today, the Fort Ancient State Memorial is listed on the National Register of Historic Places because of its importance to Ohio prehistory.
