Step outside the Western Hemisphere's third highest structure. The Ledge's glass boxes reach out 4.3 feet from the Skydeck at 1,353 feet in the air. The observation deck is open to the public free of charge. Be sure to check out all the views from up here! The Ledge is located on top of the John Hancock Center in Chicago. It was built as a luxury hotel but never opened because of problems with its design and construction. Instead, it served as a display case for art exhibitions and other events. In 2007, it was converted into a viewing platform at which point it was named one of the world's best observatories. You can walk up to the Ledge or take the elevator ride up for a 3-minute trip that takes you from the ground floor to the observation deck. As you go up in the elevator, you will have a clear view of the entire city center below. You are 70 stories above street level so be careful not to fall! The Ledge offers food and drink options including coffee, tea, snacks, and ice cream. There is also a bookstore on site if you need to read ahead of your upcoming trip. The view from the Ledge is absolutely stunning!
