    I am Willis Tower, also known as Sears Tower, the tallest building in Chicago, and a former record-holder as the tallest building in the world from 1973 to 1998. My construction began in 1970 and was completed in 1974, resulting in a 108-story skyscraper with a height of 442/527 meters (1,451/1,729 feet).
