Designated a Chicago Landmark in February 1994, the 1920’s 40-story historic building was once considered to be the tallest building in the world outside of New York City. Easily distinguished on the Chicago skyline by its “wedding cake” shape, it was co-designed by Joachim G. Giaver and Frederick P. Dinkelberg, and built as a high tech office tower for jewelers.
