CNA Center is a 600-ft (183 m), 44-story high-rise building located at 333 South Wabash Avenue in the Loop Community Area of Chicago. CNA Center is a simple, rectangular International Style building, but it is unique in that the entire building was painted bright red by Eagle Painting & Maintenance Company, Inc., turning an otherwise ordinary-looking structure into one of the most eye-catching buildings in the city. It was designed by the firm of Graham, Anderson, Probst & White and was completed in 1972. (wikipedia.org)
