We a little bit of The Cahokia Mounds State Historical site. The Cahokia Mounds State Historical Site is the largest pre-Columbian site north of Mexico. At its peak, around 1100, this metropolis stretched over 4,000 acres, encompassed about 120 earthen mounds, and hosted a population of nearly 20,000 individuals β larger than London at that time. The State of Illinois or Illinois Department of Natural Resources now protects roughly 2,200 acres of the central portion of the Site. Including 72 of the nearly 80 remaining mounds, as some mounds are situated in unprotected portions of the Site.
The Site was named a U.S. National Historic Landmark in 1965, and designated a United Nations Educational, Scientific, and Cultural Organization (UNESCO) World Heritage Site in 1982, for its significance in the pre-Contact history of North America.
One of the most prominent features of this site is Monks Mound which is the largest Pre-Columbian earthwork in the Americas and the largest pyramid north of Mesoamerica. The beginning of its construction dates from 900 to 955 CE. Located at the Cahokia Mounds UNESCO World Heritage Site near Collinsville, Illinois, the mound size was calculated in 1988 as about 100 feet (30 m) high, 955 feet (291 m) long including the access ramp at the southern end, and 775 feet (236 m) wide. This makes Monks Mound roughly the same size at its base as the Great Pyramid of Giza (13.1 acres 5.3 hectares). The perimeter of its base is larger than the Pyramid of the Sun at Teotihuacan. As a platform mound, the earthwork supported a wooden structure on the summit.
