The sculpture and AT&T Plaza are located on top of Park Grill, between the Chase Promenade and McCormick Tribune Plaza & Ice Rink. Constructed between 2004 and 2006, the sculpture is nicknamed The Bean because of its shape. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. It measures 33 by 66 by 42 feet (10 by 20 by 13 m), and weighs 110 short tons (100 t; 98 long tons).

Visitors are able to walk around and under Cloud Gate 's 12- foot (3.7 m) high arch. On the underside is the "omphalos" (Greek for " navel "), a concave chamber that warps and multiplies reflections.
