It has its rivals, but when most people say the words 'New York observation deck' and 'skyscraper', the 102-story Empire State Building immediately springs to mind. The world's tallest building from 1931 to 1977, the Empire State is currently the tallest building in NYC.
The iconic skyscraper is topped with a stepped Art Deco pinnacle that's floodlit at night and boasts holiday and commemorative colors throughout the year - green for St Patricks Day, red and pink for Valentine's Day, red and green for Christmas and so on.
After admiring the glistening Art Deco mosaics in the lobby, ride the elevator to the 86th or 102nd floors and get ready to drink in those astounding 360-degree views. The 86th-floor observatory is 1,050 feet (320 m) high, and if you pay a little extra you can visit the more intimate, enclosed observatory on the 102nd floor at 1,224 feet (373 m).
