AT&T Plaza (formerly Ameritech Plaza and SBC Plaza) is a public space that hosts the Cloud Gate sculpture. It is located in Millennium Park, which is a park built to celebrate the third millennium and which is located within the Loop community area of Chicago, Illinois in the United States. The sculpture and the plaza are sometimes jointly referred to as Cloud Gate on the AT&T Plaza. It was opened in the summer of 2004 with the initial unveiling of the sculpture during the grand opening weekend of the park. Ameritech Corporation/SBC Communications Inc. donated US$3 million for the naming right to the space. The plaza has become a place view the McCormick Tribune Plaza & Ice Rink and during the Christmas holiday season, the Plaza hosts Christmas caroling.
