Sears Tower Completed

Willis Tower, formerly named Sears Tower, is a 108-story 1,451 feet (442 m) skyscraper in Chicago, Illinois.

At the time of its completion in 1974, it was the tallest building in the world, surpassing the World Trade Center towers in New York. Currently, Willis Tower is the tallest building in the United States and the fifth-tallest freestanding structure in the world as well as the fifth tallest building in the world to the roof.

Although Sears' naming rights expired in 2003, the building continued to be called Sears Tower for several years. In March 2009 London-based insurance broker Willis Group Holdings, Ltd., agreed to lease a portion of the building and obtained the building's naming rights as part of the agreement. On July 16, 2009, at 10:00 am Central Time, the building was officially renamed Willis Tower.

The Sears Tower Chicago is located on Wacker Drive in the heart of the West Loop. It is home to Chicago's largest corporations and commuter rail stations. Upon its completion in early 1973, the Sears Tower Chicago became famous for its attractive and contemporary 110-story trophy office tower consisting of steel columns and beams. The Chicago Sears Tower also has 16,100 bronze-tinted windows.
