One World Trade Center
Construction for the building started in 2006. On April 30, 2012, One World Trade Center became New York City's tallest structure, when it surpassed the height of the Empire State Building. On May 10, 2013, the last piece of the skyscraper's antenna was put on, making the building's height 1,776 feet (541 m). The height of the building was done on purpose to refer to the year when the Declaration of Independence was signed, 1776.
