Heart of the City

The heart of Cahokia was the Grand Plaza situated between Monks Mound and the Twin Mounds. Archaeological testing has confirmed that the plaza was, in part, artificially created by filling in low areas and reducing high points to create a flat, prepared surface. It was here that public gatherings, markets and festivals would take place and the chief could address the assembled masses from Monks Mound.

The Game of chunkey, as it was called by Southeastern Indians, was apparently popular at Cahokia. Many chunkey stones, or discoidals, have been found here, such as this one from Mound 72 (left). The game was played by two men; one would roll the stone then both would throw lances or markers to where they thought the chunkey would stop rolling (above). A stone effigy pipe (right) from Oklahoma depicts a player preparing to roll a chunkey stone.

The 40-acre Grand Plaza was bordered on the north by Monks Mound and on the south by the Twin Mounds (59 & 60). Mounds 49 and 56 are located within the Plaza, mounds 51, 50, 54, and 55 mark the east side, and mounds 48 and 57 mark the western limits.

Major plazas were located north, south, east and west of Monks Mound, and smaller plazas and courtyards were found throughout the city.
