Thirteen years after the 9/11 terrorist attack, the resurrected World Trade Center has again opened for business – marking an emotional milestone for both New Yorkers and the nation.
Some staffers of publishing giant Conde Nast began working at 1 World Trade Center on Monday. The 104-story, $3.9-billion skyscraper dominates the Manhattan skyline. The publishing giant becomes the first commercial tenant in the tallest building in the United States.
It’s the centerpiece of the 16-acre site where the decimated twin towers once stood and where more than 2,700 people died on Sept. 11, 2001, buried under smoking mounds of fiery debris.
“The New York City skyline is whole again, as 1 World Trade Center takes its place in Lower Manhattan,” said Patrick Foye, executive director of the Port Authority of New York and New Jersey, which owns both the building and the World Trade Center site.

….The building is 60 per cent leased, with another 80,000 square feet going to the advertising firm Kids Creative, the stadium operator Legends Hospitality, the BMB Group investment adviser, and Servcorp, a provider of executive offices.
The government’s General Services Administration signed up for 275,000 square feet, and the China Center, a trade and cultural facility, will cover 191,000 square feet.”
