Nearly 50 years after it opened, Willis Tower remains a prominent structure in the United States architecture landscape.
It is not merely because the Chicago edifice once held the mantle as the world’s tallest structure. Its position in the Chicago skyline, history and tourist appeal – approximately 1.7 million annual visitors flock to the Skydeck on the 103rd floor – help the skyscraper retain its status as one of the most iconic construction masterpieces. Willis Tower now ranks as the world’s 23rd tallest building and is the third tallest in the Western Hemisphere. Deep dish pizza, Wrigley Field and Willis Tower are top-of-the-tongue Chicago trademarks.
