Last week in downtown Chicago, I also got a look at the 300 S. Wacker map, which was unveiled late last year and is easily visible from the west side of the Chicago River near Union Station. That’s because it’s a map as tall as a skyscraper, and who couldn’t like that?
A close up.
The giant map depicts the Chicago River and nearby streets, from Cermak to Chicago and LaSalle to Jefferson. The 300 S. Wacker building itself appears on the map as a three-dimensional red block.

Previously, 300 S. Wacker had little to distinguish it as a building, and little to catch the eye. Beacon Capital bought it last year and commissioned Elmhurst, Ill.-based South Water Signs to do the work. I’ve read that there are more art maps in the building’s lobby, backlit by LED lights; I’ll have to take a look sometime.
