Cloud Gate is a public sculpture by Indian-born British artist Sir Anish Kapoor, that is the centerpiece of AT&T Plaza at Millennium Park in 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 shape, a name Kapoor initially disliked, but later grew fond of. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. (Wikipedia)
