Formerly called the Continental Center, CNA Plaza holds the offices for CNA Insurance Company.
The project originally included the Metropolitan Tower at Michigan and Jackson. CNA Plaza North was built as an addition to that structure, and the south building was built as an addition to the north building.
Originally both of the CNA Plaza buildings were painted red. At the end of the 20th Century the paint was stripped from the north building, but the south tower kept its distinctive color.
