Lying betweenLake Michiganto the east and the Loop to the west,Grant Parkhas been Chicago's front yard since the mid-19th century. Its northwest corner, north of Monroe Street and theArt Institute, east ofMichigan Avenue, south of Randolph Street, and west of Columbus Drive, had beenIllinois Centralrail yards and parking lots until 1997, when it was made available for development by the city asMillennium Park.Today, Millennium Park trails onlyNavy Pieras a Chicago tourist attraction.
The plaza is located abovePark Grill, above and behind the McCormick Tribune Plaza & Ice Rink, adjacent to theChase Promenade, and between the North and SouthBoeing Galleries.  The plaza and sculpture sit atop the 300-seat $6 million dollarPark Grill, which opened in November 2003 behind the McCormick Tribune Plaza & Ice Rink.The surface of the plaza isconcrete.The plaza is composed of 25,200 square feet (2,340 m) of concretepavers. Each paver is 30 by 30අඟල්(76 by 76cm), and each is 2.5 අඟල් (6.4 cm) thick.
The plaza was originally named Ameritech Plaza for Ameritech Corporation, the corporate sponsor, who donated $3 million for the sculpture-hosting plaza's naming rights.By the time the park officially opened in 2004, Ameritech had merged with SBC Communications and the plaza was called SBC Plaza. When SBC acquired AT&T and subsequently changed the name from SBC to AT&T in 2005, the name of the plaza changed again.
Cloud Gatewas originally estimated to weigh 60short tons(54.4t; 53.6long tons) because it was impossible to estimate the thickness of the steel compatible with the desired aesthetics.The final piece, however, weighs 110 short tons (99.8 t; 98.2 long tons) and care had to be taken in supporting it.The roof of thePark Grill, upon whichCloud Gatesits, had to be strong enough to bear the weight. A large retaining wall separating Chicago'sMetratrain tracks from the NorthGrant Parkgarage travels along the back side of the restaurant and supports much of the sculpture's weight. This wall, along with the rest of the garage's foundation, required additional bracing before the piece was erected.In June 2004, when construction of the shell began, a large tent (pictured left) was erected around the piece in order to shield it from public view.

Because of its elevation above the McCormick Tribune Plaza & Ice Rink, the plaza has become a prime viewing location forJazz musicconcerts held during the summer at the McCormick Tribune Plaza. McCormick Tribune Plaza is located below and to the west of AT&T Plaza as well as adjacent toMichigan Avenue'sHistoric Michigan Boulevard District, which are slightly further west.
