As you ascend to breathtaking views and The Ledge, delve into the fascinating tale of Chi-Town at Skydeck's brand-new, interactive museum. This multimillion-dollar attraction is a world-class experience, celebrating Chicago's journey to becoming a metropolis and capturing its vibrant essence. Experience Chicago's most exhilarating and distinctive perspective as you step onto The Ledge's glass-floored balconies, extending 4.3 feet beyond the Willis Tower's edge, with just 1.5 inches of glass separating you from the 103 floors below.
The second-tallest building in the Western Hemisphere (the tallest if you exclude antennas), the Willis Tower offers an unparalleled view of Chicago’s skyline from its 103rd floor Skydeck, featuring four glass platforms suspended 1,353 feet in the air. Known formerly as the Sears Tower and standing at 1,450 feet with 110 stories, the tower is renowned for its iconic glass cubes called "the Ledges," which opened to the public in 2009. Each ten-foot by ten-foot platform extends 4.3 feet from the building's edge, with three layers of glass totaling one-and-a-half inches thick capable of supporting up to five tons. Designed for a sensation of floating over Chicago, the Ledges provide panoramic views spanning up to 50 miles and four states on clear days. Originally conceived to ease the cleaning of the Skydeck’s windows, these platforms were enhanced by structural glass design experts to create a virtually invisible support structure, enhancing the experience of hovering above the cityscape.
