Willis Tower

The Willis Tower is a skyscraper in Dockland.

History
The Willis Tower is the tallest building in the United States of America, standing at over 1,450 feet. One fun feature of the tower is the Skydeck, where you can feel the building sway in the wind and get a view of Michigan, Wisconsin, and Indiana. Or for you daredevils, the tower features glass balconies, so you can see why exactly you should be afraid of heights.
