Hopewell Culture National Historical Park offers views of magnificent earthworks that were built by Native American hands almost 2,000 years ago. The sites contain earthworks in the form of circles, squares, and other geometrical shapes. Many of these sites were built to a monumental scale, with earthen walls up to 12 feet high outlining geometric figures more than 1,000 feet across. This Native Culture utilized these earthworks for feasts, funerals and rites of passage.
