From Ground Zero to One World Trade Center

Reaching heights of 1,776 feet, One World Trade has surpassed the Empire State Building to become the tallest building in New York City. The installation of the silver spire topping One World Trade Center was finished on May 10, 2013, bringing the iconic structure to its full, symbolic height of 1,776 feet. The final bolts were installed to secure the spire onto the building at 8 a.m., workers said. (Mark Bonifacio/New York Daily News)
