The most extraordinary achievements of the people of the Hopewell culture were the huge earthworks they built, including walls of stone and earth to surround their ceremonial places. About two thousand years ago they built a stone wall that encloses 150 acres on a hilltop known as Spruce Hill in the scenic Paint Valley river corridor in the Arc of Appalachia region, west of Chillicothe and near Hopewell Culture National Historical Park. The Fund’s loan to the Archaeological Conservancy enabled the purchase of this 238-acre property which was to be sold at public auction.
