Expo Chicago 2012 is now open, through Sunday, September 23rd in the huge Festival Hall at Navy Pier. Organizer Tony Karman called on architect Jeanne Gang and Studio/Gang to design the 170,000 square-foot exhibition.
The domes do the job, however, of providing inescapable physical markers. Wherever you are in the huge exhibition hall, at least one of the domes is in sight, helping you to set your bearings.
