Willis Tower

Willis Tower is the heart of downtown Chicago and the future of work and play. The 110-story building is one of the tallest buildings in the world and the second tallest building in North America, making it impossible to miss when appreciating the city's skyline. The magnitude of this magnificent steel frame skyscraper can seem incomprehensible. Take a look at these facts and figures and we guarantee you won't look at America's tallest building the same way again. At Willis Tower, we are continuously expanding our eco-conscious efforts and investigating harnessing solar energy, constructing additional green roof space, and more.
