The Empire State Building is one of New York City's most famous landmarks. Built in 1930, it is 102 stories and 1,454 feet (443.2 meters) tall when measured from the ground to the very tip of its lightning rod.
Until the completion of the World Trade Center in 1972 (and once again, following the 2001 destruction), the Empire State Building was the tallest building in New York State. It is also currently the 2nd tallest skyscraper in the U.S., and 5th tallest in the world!
The Empire State Building was completed ahead of schedule after only a year and 45 days of construction. During peak periods over 3,400 people were working on it at a time, and over 7 million man-hours (the total time contributed from all the workers) was needed to finish it.
