Answer:
Poverty Point State Historical Site is a prehistoric earthwork constructed by the Poverty Point culture. The Poverty Point site is located in present-day northeastern Louisiana though evidence of the Poverty Point culture extends throughout much of the Southeastern Woodlands. The culture extended 100 miles (160 km) across the Mississippi Delta and south to the Gulf Coast. The Poverty Point site has been designated as a U.S. National Monument, a U.S. National Historic Landmark, and UNESCO World Heritage Site. Located in the Southern United States, the site is 15.5 miles (24.9 km) from the current flow of the Mississippi River, and is situated on the edge of Macon Ridge, near the village of Epps in West Carroll Parish, Louisiana.
The Poverty Point site contains earthen ridges and mounds, built by indigenous people between 1700 and 1100 BC during the Late Archaic period in North America. Archaeologists have proposed a variety of possible functions for the site including as a settlement, a trading center, and/or a ceremonial religious complex.
The 402-acre property now operated as the Poverty Point State Historic Site contains "the largest and most complex Late Archaic earthwork occupation and ceremonial site yet found in North America".Euroamericans described the site in the 19th century. Poverty Point has been the focus of professional archaeological excavations since the 1950s. The earthworks are named after a 19th century plantation on the property.
