#1 The Ledge - Willis Tower, Chicago

Formerly the Sears Tower, the Willis Tower opened in 1974, and attracts over 1.3 million people annually, all wanting to stand on The Ledge. The Skydeck houses a series of glass bays, jutting out 4.3 feet from the building and 103 floors over the street, with visitors marveling at the sight of Wacker Drive below them.
