The Grand Plaza is a large open plaza that spreads out to the south of Monks Mound. Researchers originally thought the flat, open terrain in this area reflected Cahokia's location on the Mississippi's alluvial flood plain, but instead soil studies have shown that the landscape was originally undulating. In one of the earliest large-scale construction projects, the site had been expertly and deliberately leveled and filled by the city's inhabitants. It is part of the sophisticated engineering displayed throughout the site. The Grand Plaza covered roughly 50 acres (20 ha) and measured over 1,600 ft (490 m) in length by over 900 ft (270 m) in width. It was used for large ceremonies and gatherings, as well as for ritual games, such as chunkey. Along with the Grand Plaza to the south, three other very large plazas surround Monks Mound in the cardinal directions to the east, west, and north.
