The 1,454 foot Empire State Building is easy to find in a city filled with more than 7,000 high-rises. This Art Deco structure was the world’s tallest when it opened in 1931. The title was held until 1970. On the 102nd floor is an observation deck with outstanding views of New York City. Be prepared to endure a long waiting line. Over four million tourists annually ride the elevator to experience the famous pinnacle. The American Society of Civil Engineers listed the Empire State Building among the Seven Wonders of the Modern World for engineering.
