Cloud Gate, a sculpture by Indian-born British artist Anish Kapoor, is the centerpiece of the AT&T Plaza in Millennium Park of Chicago.
Constructed between 2004 and 2006, the sculpture is nicknamed "The Bean" because of its bean-like shape. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. It is 10 by 20 by 13 m, and weighs 110 tons.
