Architecture

The Empire State Building was designed by Shreve, Lamb and Harmon in the Art Deco style. The Empire State Building is 1,250 ft (381 m) tall to its 102nd floor, or 1,453 feet 8 + 9 ⁄ 16 inches (443.092 m) including its 203-foot (61.9 m) pinnacle. It was the first building in the world to be more than 100 stories tall, though only the lowest 86 stories are usable. The first through 85th floors contain 2.158 million square feet (200,500 m) of commercial and office space, while the 86th floor contains an observatory. The remaining 16 stories are part of the spire, which is capped by an observatory on the 102nd floor; the spire does not contain any intermediate levels and is used mostly for mechanical purposes. Atop the 102nd story is the 203 ft (61.9 m) pinnacle, much of which is covered by broadcast antennas, and surmounted with a lightning rod.
