Monks Mound:
Monks Mound is the largest prehistoric earthwork in the Americas. Its base covers over 14 acres, and it rises to a height of 100 feet. It contains and estimated 22 million cubic feet of earth, all hand-carried in baskets from the many borrow pits throughout the Cahokia site.
It was not built all at once, but in a series of stages, mostly from AD 950-1200. Core-drillings through the mound suggest eight to 14 building stages. Excavations at various locations found indications of a stairway on the South Ramp, several buildings and a small mound rebuilt eight times on the First Terrace; a large temple structure on the Fourth Terrace; evidence of a French chapel and historic Indian occupation (1730s) on the First Terrace; and the discovery of the Birdman Tablet on the east side of the mound.
Recent tests confirm that the First Terrace was a late addition to the front of the mound and drilling deep beneath the Second Terrace encountered a large mass of stone cobbles whose function is unknown at this time. The Mississippians were also doing soil engineering, selecting and placing specific soils for strength or drainage.
It is called Monks Mound because a group of French Trappist Monks lived on a nearby mound from 1809-1913 and planted gardens, fruit trees and wheat on the terraces of this mound.
The Fourth Terrace building was probably the residence of the leader and the religious/political focus of this urban center. A fenced courtyard with a huge post in the center enclosed the fourth terrace.
In the 1830s, Amos Hill built his farm complex on the Third Terrace and removed a small mound on the southeast corner. He is buried on the northwest corner of the Fourth Terrace.
