The Cahokia Mounds State Historic Site /kxc9x99xcbx88hoxcax8akixc9x99/ (11 MS 2)[2] is the site of a pre-Columbian Native American city (which existed c. 1050xe2x80x931350 CE[3]) directly across the Mississippi River from modern St. Louis, Missouri.
[4] The park covers 2,200 acres (890xc2xa0ha), or about 3.5 square miles (9xc2xa0km2), and contains about 80 mounds, but the ancient city was much larger.
At its apex around 1100 CE, the city covered about 6 square miles (16xc2xa0km2) and included about 120 manmade earthen mounds in a wide range of sizes, shapes, and functions.
The city's complex construction of earthen mounds required excavation, movement by hand using woven baskets, and construction involving 55 million cubic feet of earth, much of which was accomplished over a matter of just decades.
Its highly planned ceremonial plazas sited around the mounds with homes for thousands connected by laid out pathways and courtyards suggest the location served as a central religious pilgrimage city.

[26] If the highest population estimates are correct, Cahokia was larger than any subsequent city in the United States until the 1780s, when Philadelphia's population grew beyond 40,000.
Monks Mound is the largest structure and central focus of the city: a massive platform mound with four terraces, 10 stories tall, it is the largest man-made earthen mound north of Mexico.
Excavation on the top of Monks Mound has revealed evidence of a large building, likely a temple or the residence of the paramount chief, which would have been seen throughout the city.
In one of the earliest large-scale construction projects, the site had been expertly and deliberately leveled and filled by the city's inhabitants.
Beyond Monks Mound, as many as 120 more mounds stood at varying distances from the city center.
In general terms, the city center seems to have been laid out in a diamond-shaped pattern about 1xc2xa0mi (1.6xc2xa0km) from end to end, while the entire city is 5xc2xa0mi (8.0xc2xa0km) across from east to west.
