Poverty Point Historic Site is a collection of prehistoric earthworks made by members of the Poverty Point Culture located in present-day Northeastern Louisiana. The site contains a collection of ridges and mounds constructed from around 1700 B.C.E. to 750 B.C.E. during the Archaic Period. At its height, Poverty Point was the most complex and most populous settlement in North America. The site is significant because of its complexity as well as the lingering mystery of the site's original purpose.
