List of tallest buildings in New York City
A second skyscraper boom began in the early 1960s. Since then, the city has seen the completion of nearly 70 structures rising at least high, including the twin towers of the World Trade Center. One WTC also known as the North Tower, was the tallest building in the world from 1972 until 1973 and the tallest building in New York City until 2001. The North Tower, as well as the other six buildings in the World Trade Center complex, were destroyed in the September 11 attacks of 2001. One World Trade Center began construction in 2006 as the lead building of the new World Trade Center complex; upon its topping out in May 2013, the skyscraper surpassed the Willis Tower to become the tallest building in the United States.
