One World Trade Center, America's tallest building, on Monday welcomed
its first tenants, publishing group Conde Nast, in a symbolic moment 13
years after the 9/11 attacks that brought down the original Twin Towers.
Publishing company Conde Nast began moving on Monday into One World Trade Centre, a 104-storey skyscraper that dominates the Manhattan skyline.
The skyscraper - at 1,776ft (541m), America's tallest building - is
the centrepiece of the site where the twin towers once stood.
