The Blue Cross Blue Shield Tower (BCBS) is on the north end of Millennium Park along E. Randolph Street at the NE corner of Randolph and Columbus Drive, in Chicago, Illinois, United States. It is home to the headquarters of Health Care Service Corporation.
The building's address is 300 E. Randolph Street and is next to the Aon Center. Original plans to connect the two buildings via an underground pedway never came to fruition.
Architect James Goettsch of Goettsch Partners designed the building. The 33-story first phase was completed in 1997 under the firm name of Lohan Associates (now Goettsch Partners). The 24-story second phase started in 2007 and was completed in 2010.
