Willis Tower is Chicago's tallest building (and one of the world's loftiest). Breathe deeply during the ear-popping, 70-second elevator ride to the 103rd-floor , then stride to one of the glass-enclosed ledges that jut out in midair for a knee-buckling perspective straight down some 1400ft.
A bit of history: it was the Sears Tower from its completion in 1973 until insurance broker Willis Group Holdings bought the naming rights in 2009. The building held the title of world's tallest building for almost a quarter century, surpassed by NYC's One World Trade Center in 2013.
