Happy #WorldArchitectureDay! 🏛️ We love our building’s many architectural details, and we can’t wait to show them off at Open House Chicago by chiarchitecture, October 17-18. Add us to your itinerary for this free city-wide architectural festival and explore our 10 floors of history and detail, including our Venetian courtyard and 125-year-old Art Nouveau murals.
