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.
