Fearless: Five-year-old Anna Kane spreads out on the floor of the 10ft square box which is 1,353 ft up.
Thrill seekers: The boxes jut out four feet from the building and were specifically designed to attract visitors. The Willis Tower has always been about superlatives – tallest, largest, most iconic.
The Ledge is the world’s most awesome view, the world’s most precipitous view, the view with the most wow in the world. The balconies are 10ft high and 10ft wide, can hold five tons, and have glass which is 1.5 inch thick.
Inspiration came from the hundreds of forehead prints visitors left behind on The Skydeck windows every week. Now, staff have a new glass surface to clean: floors!
Architect Ross Wimer said: ‘We did studies that showed a 4′ X 4′ deep enclosure makes you feel like you’re detached from the building particularly since there’s only room for one row of people.’
The Ledge is accessible from The Skydeck which attracts 25,000 visitors on clear days. They each pay $15 to take an elevator ride up to the 103rd floor of the 110-story office building that opened in 1973.
