Willis Tower Skydeck: Stepping Out Into the Chicago Sky

Chicago, Illinois, United States

Hovering 103 stories above the pavement, these clear glass cubes let you walk out past the skyscraper's edge for a dizzying look at the city below.

Standing on the 103rd floor of what many locals still affectionately call the Sears Tower, you aren't just looking at the Chicago skyline—you are hanging over it. The Ledge consists of four specialized glass balconies that jut out from the building's face, providing a perspective that was once reserved for window washers and birds.

At 1,353 feet in the air, the sensation of nothingness beneath your shoes is enough to challenge even the strongest constitution.

Why It Stands Out

The inspiration for these transparent perches actually came from the visitors themselves. For years, staff noticed that tourists were constantly pressing their faces against the glass to peer straight down, leaving a never-ending trail of forehead smudges.

To solve this and enhance the experience, designers created these glass cubes that extend 4.3 feet past the tower’s exterior wall. The engineering behind the floating sensation is as impressive as the view.

The city is also home to the impressive Tiffany Dome. Each box is built from layered structural glass engineered to hold the weight of the visitors who step inside.

By removing the visible steel supports from the perimeter, the architects created a seamless transition into the sky. Visitors seeking more glass architecture can visit the Garfield Park Conservatory.

On a clear afternoon, the visibility stretches for 50 miles, encompassing parts of four different states. Whether you are watching the tiny toy-like cars move along Wacker Drive or looking out at the vast blue of Lake Michigan, the 110-story vantage point remains one of the most iconic urban experiences in the world.

Before You Go

The Skydeck is a popular destination, so expect a wait during peak hours. To find the entrance, head to the south side of Jackson Boulevard.

Another local landmark is the themed Oz Park. While the building was renamed the Willis Tower in 2009, you will likely still hear it referred to by its original name during your travels through the city.
