Willis Tower (formerly named and still commonly referred to as Sears Tower) is a 108-story, 1,451-foot (442 m) skyscraper in Chicago, Illinois. At the time of its completion in 1973, it was the tallest building in the world, surpassing the World Trade Center towers in New York, and it held this rank for nearly 25 years. The Willis Tower is the tallest building in the United States and the seventh-tallest freestanding structure in the world. The skyscraper is one of the most popular tourist destinations in Chicago, and over one million people visit its observation deck each year.
Although Sears' naming rights expired in 2003, the building continued to be called the Sears Tower for several years. In March 2009, London-based insurance broker Willis Group Holdings agreed to lease a portion of the building, and obtained the building's naming rights. On July 16, 2009, the building was officially renamed the Willis Tower. On August 13, 2012, United Airlines announced it will be moving its corporate headquarters from 77 West Wacker Drive to the Willis Tower.

Famous quotes containing the word tower:
“With the noise of the mourning of the Swattish nation!
Fallen is at length
Its tower of strength;
Its sun is dimmed ere it had nooned;
Dead lies the great Ahkoond,
The great Ahkoond of Swat
—George Thomas Lanigan (18451886)
