Here a photo of Chicago city showing the Willis Tower (higher building).

The Willis Tower (colloquial: Sears Tower, its name for 36 years) is a 110-story, 1,450-foot (442.1 m) skyscraper. At completion in 1973, it surpassed the World Trade Center in New York City to become the tallest building in the world, a title that it held for nearly 25 years.

The Willis Tower observation deck, called the Skydeck, opened on June 22, 1974. In January 2009, a major renovation of the Skydeck was begun, including the installation of retractable glass balconies which extend approximately 4 feet (1.2 m) from the facade of the 103rd floor, overlooking South Wacker Drive. The all-glass boxes, informally dubbed "The Ledge", allow visitors to see the street below.
