Willis Tower Skydeck in Chicago is an observation deck located on the 103rd floor of the Willis Tower, offering panoramic views stretching across the city and neighboring states from approximately 412 meters above street level, according to the facility’s operators.
Willis Tower Skydeck Height and Architectural Overview
The Willis Tower, situated in Chicago’s central Loop district, reaches a height of well over 400 meters including its roof and antennas, with the Skydeck positioned on the 103rd floor. According to historical building data, the skyscraper was designed by the architectural firm Skidmore, Owings & Merrill and opened to the public in 1974 following its construction in the early 1970s. Originally planned and known as the Sears Tower, the building was officially renamed the Willis Tower in 2009 following a leasing agreement and brand update.
The Ledge: Glass Balconies and Engineering Specifications
A defining feature of the attraction is “The Ledge,” a series of glass-floored balconies that extend roughly 1.3 meters beyond the building’s western glass facade, according to technical disclosures by the operators. Installed by Berglund Construction, these rectangular, five-sided glass boxes consist of multiple layers of laminated safety glass that total approximately 3.8 centimeters in thickness. Each structural box is engineered to support up to five tons of weight, featuring fully glazed side walls, ceilings, and floors that retreat along tracks back into the building facade for routine maintenance and cleaning.
