Stop, stop....Sita wants us to stop...she has spotted a UNESCO world heritage site....
After AD 1200, the population began to decline and the site was abandoned by AD 1400.
However, it is the building accomplishments and cultural developments of the earlier Indians that make this site significant. They constructed more than 120 earthen mounds over an area of six square miles, although only 80 survive today.
These industrious people moved over an estimated 55 million cubic feet of earth in woven baskets to create this network of mounds and community plazas.
As the largest prehistoric earthen construction in the Americas, Monks Mound is a testament to the sophisticated engineering skills of these people.
Additionally, they built several "Woodhenges," large post-circle monuments that appear to have been used as calendars, and they also constructed several defensive palisades nearly two-miles long around the central ceremonial precinct.
This agricultural society may have had a population of 10–20,000 at its peak between 1050 and 1150.
