Cloud Gate is a public sculpture by Indian-born British artist Anish Kapoor, that is the centerpiece of Grainger Plaza at Millennium Park in the Loop community area of Chicago. Constructed between 2004 and 2006, the sculpture is nicknamed "The Bean" because of its shape, a name Kapoor 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.
