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. Public gatherings, markets, and festivals took place there, and the chief could address assembled masses from Monks Mound. A view of central Cahokia looking north between the Twin Mounds across the Grand Plaza to Monks Mound includes a chunkey field and traders’ shelters along the plaza’s edge in front of the homes of the elite. The game of chunkey, as it was called by Southeastern Indians, was apparently popular at Cahokia, and many chunkey stones, or discoidals, have been found there, including one from Mound 72. The game was played by two men: one rolled the stone, then both threw lances or markers to where they thought the chunkey would stop rolling. The forty-acre Grand Plaza was bordered on the north by Monks Mound and on the south by the Twin Mounds (59 and 60). Mounds 49 and 56 were located within the plaza, mounds 51, 50, 54, and 55 marked the east side, and mounds 48 and 57 marked 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.
