The cloud gate or bean sculpture by atrist Anish Kapoor AT&T Plaza in Millennium Park within the Loop community area of Chicago

Cloud Gate, a public sculpture by Indian-born British artist Anish Kapoor, is the centerpiece of the AT&T Plaza in Millennium Park within the Loop community area of Chicago, Illinois. 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 legume-like shape. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. It is 33 feet by 66 feet by 42 feet (10 m × 20 m × 13 m), and weighs 110 short tons (99.8 t; 98.2 long tons). Kapoor's design was inspired by liquid mercury and the sculpture's surface reflects and distorts the city's skyline. Visitors are able to walk around and under Cloud Gate's 12-foot (3.7 m) high arch. On the underside is the omphalos, a concave chamber that warps and multiplies reflections. The sculpture builds upon many of Kapoor's artistic themes, although many tourists simply view the sculpture and its unique reflective properties as a photo-taking opportunity. The sculpture was the result of a design competition.
