World Trade Center reopens for business

Thirteen years after the 9/11 terrorist attack, the resurrected World Trade Center is again opening for business. Publishing company Conde Nast will started moving in on Monday into One World Trade Center, a 104-storey skyscraper that dominates the Manhattan skyline. Only about 170 of his company’s 3,400 employees are moving in now. Still, the opening marks an emotional milestone for both New Yorkers and the nation.

The New York City skyline is whole again, as One World Trade Center takes its place in Lower Manhattan.

The skyscraper - at 541m the US tallest building - is the centrepiece of the site where the Twin Towers once stood. More than 2,700 people died on 11 September 2001, buried under smoking mounds of fiery debris. The building’s eight-year construction came after years of political, financial and legal infighting that threatened to derail the project. It cost $3.9b. But lower Manhattan has prospered in recent years. Today, about 60,000 more residents now live there - three times more than before 9/11.
