5 Architecture Facts About the Willis Tower

For almost 25 years the Willis Tower, more commonly known as Sears Tower, held the title for the tallest building in the U.S. Second place isn’t bad, right? And as the 12th tallest in the world at a height of 1,451 feet, it is Chicago’s most beloved skyscraper.

Commissioning The Building

In order to house their rapidly growing company, Sears commissioned architects Skidmore, Owings & Merrill in 1969. Architect Bruce Graham and engineer Fazlur Rahman Kahn led.

Advancements in Architecture

The Willis Tower was the first to ever use a bundled tube structure. Kahn’s design was so revolutionary that it was later used for the world’s tallest building, the Burj Khalifa.

Inspiration

Graham’s design was inspired by a cigarette ad. He demonstrated the concept to a colleague by pulling cigarettes out of a pack to illustrate the 9 tubes at different heights.

How was it Built

Construction began in April of 1971 and was finished by May 1973. Economically efficient for a building its size, the cost to build was $150 million, about $800 million today.

The Skydeck

Willis Tower’s observation deck is what makes it celebrated. At 1,353 feet, visitors can feel the building sway on a windy day and see over the plains of Illinois on a clear day.

What People Are Saying About Willis Tower

Wonderful, entertaining and educational!

The architecture cruise is a trip down the 3 branches of the Chicago River while your guide points out relevant buildings and elements of architecture that are historically and otherwise significant. Our guide, Kevin, is a true Renaissance man. He was able to relate the architectural elements with the history of the period, the politics of the period, and the science and engineering necessary to make the architecture happen. At the end of the cruise, he produced a harmonica and began playing an authentic Chicago blues riff while singing an architecture song that I'm sure he wrote. Not only did he teach, he made the architecture come alive! It would be impossible for anyone to see Chicago in the same way after taking his guided cruise. Very highly recommended! Enjoy! I hope you have a similar experience.

Excellent value to enjoy all the major attractions in Chicago

Very good value, and good customer service. Was caught out though, by the restriction of one boat tour per day.
