Fascinating tour of Chicago’s earliest skyscrapers, led by Anthony, our guide from the Chicago Architecture Center. He introduced us to buildings designed by renowned architects inc Louis Sullivan, Daniel Burnham, William LeBaron Jenney & Frank Lloyd Wright, among others. Highlights for me included the Auditorium, Monadnock, Rookery & Marquette buildings. Interiors of the Rookery & Marquette (inc Tiffany mosaics!) were stunning. Tony was very engaging, fun & knowledgeable. He pointed out many design & architectural details that we would have otherwise missed, in addition to adding very interesting historical & technological context at each stop. Highly recommended!
