Photographer records 1 World Trade Center's spectacular rise Monday marked a major milestone in lower Manhattan's resurgence as the first tenants moved into 1 World Trade Center. The 175 employees of Condé Nast are the vanguard of a huge influx of tenants from the publishing giant. Eventually, around 3,400 Condé Nast workers will be based at 1World Trade Center, occupying 1.2 million square feet in the 104-story tower. A concrete symbol of America's resilience following the Sept. 11 attacks, New Yorkers have paid close attention to the building of 1World Trade Center. Watching construction unfold from across the East River, one Brooklyn-based photographer decided to produce a stunning visual record of the skyscraper's rise. In February 2011 Benjamin Rosamond set up two cameras in the window of his apartment, which he used to shoot a daily record of the tower through August 2014. "It's a confluence of (my) interests and circumstances," Rosamond told FoxNews.com, explaining that he moved into his apartment in Prospect Heights just before the tower became visible on the skyline. I was lucky enough to have a front-row view. The end result condenses 1,200 photos into two spectacular time-lapse minutes, charting the construction of America's tallest building. Rosamond winnowed a total of 30,000 photos to document the new Manhattan skyline. "It's about three-and-a-half years worth of footage whittled down to photos from sunrise, when it's at its best," he explained.
