Discovering the Iconic Willis Tower: A Chicago Landmark

When you think of Chicago, one structure likely comes to mind: the Willis Tower. Formerly known as the Sears Tower, this architectural marvel is not just a skyscraper; it’s a symbol of the Windy City. Standing at a towering height of 1,450 feet, Willis Tower was once the tallest building in the world and remains one of the most recognizable landmarks in the United States. In this blog post, we’ll explore the history, significance, and attractions that make the Willis Tower a must-visit destination for both locals and tourists.

A Brief History

Constructed between 1970 and 1973, the Willis Tower was originally known as the Sears Tower, named after the retail giant that occupied the majority of its office space. Designed by the architectural firm Skidmore, Owings & Merrill, the building’s unique design features a bundled tube structure, allowing it to rise higher than its predecessors while providing stability against the strong winds that often sweep through Chicago.


For over two decades, the Willis Tower held the title of the tallest building in the world, a feat that not only placed Chicago on the global map but also spurred a surge of skyscraper construction in the city. In 2009, the insurance broker Willis Group Holdings acquired naming rights, and the building was officially renamed the Willis Tower. Despite the name change, the building continues to be fondly referred to as the Sears Tower by many Chicagoans.

Architectural Marvel

The Willis Tower is an engineering masterpiece, showcasing the innovative design and construction techniques of the 20th century. The building comprises 110 floors and is made of a series of nine square tubes stacked together. This design maximizes usable floor space while minimizing wind resistance, allowing it to withstand gusty Chicago weather. The exterior is clad in sleek black glass, which not only contributes to its striking appearance but also helps regulate temperature within the building.

Visitors often marvel at the tower’s unique Skydeck, located on the 103rd floor, where they can take in breathtaking panoramic views of the Chicago skyline, Lake Michigan, and even the neighboring states on clear days. The Skydeck is particularly famous for its glass-bottomed balconies, known as "The Ledge," which extend out 4.3 feet from the building, giving brave visitors the feeling of walking on air as they look straight down to the streets below.
