This 1976 Philip Johnson and John Burgee structure is two buildings of trapezoidal shape. A 10-foot-wide slot separates the 36-story towers, which are composed of dark bronze and aluminum. The spaces are connected by a street-level plaza enclosed in a glass atrium. It is the winner of more design awards than any other downtown building.
