The Empire State Building is the first building to have more than 100 floors. It possesses the only address with the zip code 10118. It was built in 16 months with a total cost just shy of $41 million.

The building is clad in Indiana limestone and granite, with the mullions lined in shiny aluminium. There are in all 6,500 windows, with spandrels sandblasted to blend their tone to that of the windows, visually creating the vertical striping on the facade. The 102nd floor was originally a landing platform with a dirigible gangplank.
