The Empire State Building is a 102-story[c] Art Deco skyscraper in Midtown Manhattan, New York City. It was designed by Shreve, Lamb & Harmon and completed in 1931. The building has a roof height of 1,250 feet (380 m) and stands a total of 1,454 feet (443.2 m) tall, including its antenna. Its name is derived from “Empire State”, the nickname of New York, which is of unknown origin. The Empire State Building stood as the world’s tallest building for nearly 40 years until the completion of the World Trade Center’s North Tower in Lower Manhattan in late-1970. Following the September 11 attacks in 2001, it was again the tallest building in New York City until the new One World Trade Center surpassed it while under construction in April 2012. As of 2019, the building is the seventh-tallest building in New York City, the sixth-tallest completed skyscraper in the United States, and the 45th-tallest in the world. It is also the sixth-tallest freestanding structure in the Americas.
