Willis Tower Skydeck and the glass ledges above Chicago
Published on 09/23/2026 at 19:42 | Editorial responsibility: Rafael MĂĽller, Editor-in-Chief AD HOC NEWS
Willis Tower Skydeck occupies the 103rd floor of Chicago’s Willis Tower, where glass balconies project beyond the skyscraper’s façade. The Ledge places visitors above the city with transparent flooring beneath their feet. The tower’s black aluminium, bronze-tinted glass and stepped outline form the setting for this elevated view.
Glass balconies above the Chicago Loop
The Ledge consists of glass-enclosed balconies extending from Willis Tower. Each projects about 4.3 feet from the building, with the glass floor suspended 1,353 feet above Wacker Drive. The balconies present Chicago’s streets, river and buildings from a position beyond the tower’s main wall.
The Skydeck sits within a 110-storey skyscraper at 233 South Wacker Drive. Its view reaches across Chicago’s Loop and towards the city’s wider urban landscape. Skydeck tower history records the building’s completion in May 1973 and identifies the observation level above the city.
Willis Tower’s bundled-tube silhouette
Willis Tower was designed by Skidmore, Owings & Merrill, with Bruce Graham as architect and Fazlur Rahman Khan as structural engineer. Its frame uses bundled tubes, a system formed from connected structural sections that rise together before ending at different heights.
This arrangement creates the tower’s recognisable stepped profile. The building reaches about 442 metres (1,450 feet), excluding its broadcast antennas, and contains 110 storeys. Black aluminium and bronze-tinted glass cover the exterior, giving the shaft a dark, reflective appearance against Chicago’s skyline. SOM project details describe the structural tubes, façade materials and the tower’s completion period.
From Sears Tower to Willis Tower Skydeck
The skyscraper opened as Sears Tower in 1973. Sears, Roebuck and Company occupied it as a headquarters until 1995, while the building retained its original name for decades. The name Willis Tower entered use in 2009.
The Skydeck opened in 1974 on the 103rd floor. The Ledge followed in 2009, adding glass balconies to the observation platform. A visit therefore combines two visible layers: a major twentieth-century office tower and a later viewing feature that projects beyond its façade. Britannica tower history places the Skydeck on the 103rd floor and identifies the building’s earlier Sears Tower name.
The surrounding Skydeck presentation includes exhibitions about Chicago’s history, neighbourhoods, architecture and landmarks. These displays connect the high-level view with the city below, while the tower itself remains visible through its structural form, height and materials. Chicago architecture details identifies the Skydeck and The Ledge as features of the Willis Tower experience.
