Willis Tower ( Sears Tower )

Last crawled date: 1 year ago

Willis Tower, formerly named Sears Tower, is a 108-story 1,451 feet 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. 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. However, 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. In January 2009, the Skydeck began a major renovation including the installation of glass balconies extending approximately four feet over Wacker Drive from the 103rd floor. The all-glass boxes allow visitors to look through the floor to the street 1,353 feet below. The building's official address is 233 South Wacker Drive, Chicago, Illinois 60606.
