Willis Tower Skydeck and its glass ledge over Chicago
Published on 08/27/2026 at 21:13 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
High above downtown Chicago, Willis Tower Skydeck turns a corporate skyscraper into an encounter with height, culminating in glass balconies that project visitors out over the city streets far below.
From Sears Tower to Willis Tower Skydeck
Willis Tower rose in the 1970s as the headquarters of Sears, Roebuck and Company, a retail giant that once dominated mail-order and department store trade across the United States.Built for Sears Skidmore, Owings & Merrill, the Chicago-based practice commonly known as SOM, designed the structure as a bundled tube skyscraper whose stacked, offset shafts create the familiar stepped silhouette on the city’s skyline.Height 442.1 m The tower reaches 442.1 m (1,451 ft) to its main roof, excluding the broadcast antennas that extend higher.
The observation deck on the 103rd floor opened in 1974, offering a high-altitude public viewpoint within a building otherwise devoted to offices.Skydeck opened in 1974 Set more than 400 m above street level, the deck established Willis Tower as a place to look out over Chicago’s grid of streets, the Chicago River and Lake Michigan, as well as the flat landscapes of Illinois and neighbouring states on clear days.Views up to 50 miles
The 103rd floor and the experience of height
Skydeck Chicago occupies the 103rd floor of the tower, at an elevation of 1,353 ft (412 m) above the pavements of South Wacker Drive.Skydeck 1,353 feet above ground Access is by lift from the tower’s lobby, emerging into a circuit of interior viewing areas with large windows facing in multiple directions across the city and the surrounding region. From this level, the Chicago River’s bends and junctions are visible, as are the blocks of the Loop, the lakefront and the more distant belts of neighbourhoods stretching towards the horizon.Highest observation deck in the United States
At this height, the difference between conventional viewpoints and Skydeck becomes clear in the way the city reads as a diagram of streets, rail lines and waterways rather than individual façades. The position near the centre of Chicago’s business district places many of the city’s other towers within view, but they sit notably lower than the main roof of Willis Tower, underscoring the building’s continued prominence on the skyline.
The Ledge: glass balconies above Wacker Drive
In 2009, Skydeck added The Ledge, a set of glass-floored balconies that project from the west face of Willis Tower and allow visitors to step out beyond the original façade.The Ledge at Skydeck Chicago Each balcony forms a five-sided glass box that extends about 4.3 ft (1.3 m) out from the building, with floor, walls and ceiling all made from laminated structural glass panels.glass balconies extend 4.3 feet Standing on one of these boxes places only around 1.5 inches of glass between visitors’ shoes and the drop to the street over 100 storeys below.three layers of half-inch glass
The Ledge’s balconies sit on rails that allow them to retract fully into the building for cleaning and maintenance, and they are engineered to support loads of up to five short tons, or approximately 10,000 lbs.boxes built to hold 10,000 lbs The tower façade around them remains in place, so the boxes read as clear protrusions from the dark metal and glass exterior of Willis Tower when seen from ground level on South Wacker Drive. Inside, they form a sequence along the west side of the deck, each allowing a direct downward view to the traffic and pavements below and to the Chicago River beyond.
