PIONEER, LOUISIANA—The monumental earthworks at Poverty Point are one of seven sites from around the world that have been added to the list of UNESCO World Heritage sites, according to a report from Reuters. The 3,400-year-old Poverty Point complex was a major political, trade, and ceremonial center built by hunter gatherers. It consists of six mounds and six C-shaped ridges surrounding a central plaza. One of the mounds is about 2,000 years older than the others. “The impressive site survives as a testament to Native American culture and heritage,” the U.S. State Department responded to the announcement in a statement.
