Willis (Sears) Tower - Chicago , USA

🇺🇸 Welcome to Chicago!
 

This model was created by Dany Sánchez.

The Willis Tower is a 108-story, 1,450-foot (442.1 m) skyscraper in Chicago, Illinois, United States. It was commissioned by Sears, Roebuck & Co. in 1969 for its new headquarters, and built between 1971 and 1974. Up until 2009, it was named Sears Tower, but after Sears sold it and insurance conglomerate Willis Group moved in as tenant, it was renamed as part of the lease. The name could possibly change again in 2024 when the lease expires. 

At completion, the Sears Tower surpassed the original World Trade Center in New York City to become the tallest building in the world, a title that Sears Tower held for nearly 25 years; it was also the tallest building in the Western Hemisphere for 41 years, until the new One World Trade Center surpassed it in 2013.

For such an old building, it is still the third-tallest building in the United States and the Western hemisphere – and the 23rd-tallest in the world. 

Engineer Fazlur Rahman Khan is credited for the innovative and cost-effective approach of 9 square tubes arranged in a 3x3 grid, with different heights (from Wikipedia).
