Hearst Tower, New York City
The first skyscraper to break ground in New York City after Sept. 11, 2001, Hearst Tower houses the headquarters of the Hearst Corporation publishing empire. The building's six-story base was originally commissioned by William Randolph Hearst in 1928 to be used as the foundation for a skyscraper, but the Great Depression caused plans to grind to a halt.
The new 46-story glass and steel tower, designed by architect Norman Foster and built above the original base, was completed in 2006, almost 70 years after Hearst's vision was born. It has the distinction of being New York City's first "green" office building.
