The Empire State Building is a 103-story skyscraper located in Midtown Manhattan, New York City, at the intersection of Fifth Avenue and West 34th Street. It has a roof height of 1,250 feet (380 m), and with its antenna spire included, it stands a total of 1,454 feet (443 m) high. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for nearly 40 years, from its completion in early 1931 until the topping out of the original World Trade Center's North Tower in late 1970. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York (although it was no longer the tallest in the US or the world), until One World Trade Center reached a greater height on April 30, 2012. The Empire State Building is currently the fourth-tallest completed skyscraper in the United States (after the One World Trade Center, the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 23rd-tallest in the world (the tallest now is Burj Khalifa, located in Dubai). It is also the fourth-tallest freestanding structure in the Americas.
