The Sears Tower is the highest building of Chicago and at the same time also at present highest Wolkenkratzer in the USA.

Itafter a three-year construction period in the year 1974 in Chicago one opened. With a height of 442 meters (with antenna of 527 meters) it was until 1997 the highest building of the world. In the year 1997 the Petronas Towers finally lodged a complaint in Kuala Lumpur (altogether 452 m) the title of the highest building for itself - however in the consequence violently about the crucial mass it was argued in particular whether the antenna height or the roof height is relevant.
