World Trade Center reopens in NY, 13 years after attacks

Thirteen years after the 9/11 terrorist attack, the resurrected World Trade Center has opened for business — marking an emotional milestone for both New Yorkers and the nation.

‘‘The New York City skyline is whole again,’’ said Patrick Foye, executive director of the Port Authority of New York and New Jersey, which owns both the building and the 16-acre World Trade Center site.

Steps away from the new tower are two memorial fountains that were built on the footprints of the destroyed towers, a reminder of the more than 2,700 people who died in the terrorist attack.

Conde Nast, the publisher of Vogue, The New Yorker, and Vanity Fair, is expected to move in about 3,000 more employees by early next year, eventually occupying 25 floors of the $3.9 billion, 104-story tower, the nation’s tallest building.

Amid Monday’s celebratory tour of portions of 1 World Trade Center, Conde Nast officials declined to comment on employees’ possible fears about working in the new building. Some employees acknowledged they were nervous about working in a skyscraper that could again be a terrorist target.

Its chief architect, T.J. Gottesdiener, said the high-rise was built with steel-reinforced concrete that makes it as attack-proof as possible — much stronger than the original towers, which collapsed on themselves after they were struck by hijacked airplanes.

After 9/11, he said, architects took pains to figure out new ways to make a high-rise safer, working with the New York Fire Department, buildings officials, and police, while learning from new techniques employed in construction in cities worldwide.

One World Trade Center is 60 percent leased, with another 80,000 square feet going to the advertising firm Kids Creative; the stadium operator Legends Hospitality; BMB Group, an investment adviser; and Servcorp, a provider of executive offices.

The US General Services Administration signed up for 275,000 square feet. China Center, a trade and cultural facility, will have 191,000 square feet.
