Cloud Gate is a public sculpture by artist Anish Kapoor that is the centerpiece of Grainger Plaza at Millennium Park in the Loop community area of Chicago, Illinois, United States. Constructed between 2004 and 2006, the sculpture is nicknamed "The Bean" because of its shape, a name Kapoor initially disliked but later grew fond of. Made up of 168 stainless steel plates welded together, its reflective and highly polished exterior has no visible seams. It measures 33 by 66 by 42 feet, and weighs 110 short tons. The sculpture and its plaza are located above Millennium Hall, between the Chase Promenade and McCormick Tribune Plaza & Ice Rink.
