Thirteen years after the tragic 9/11 attacks, the World Trade Center has officially re-opened its doors for business. On Monday, media company Condé Nast began moving into One World Trade Center, which is currently the tallest building in the Western Hemisphere with a spire that reaches a symbolic 1,776 feet. More than 2,700 people were killed on September 11, 2001 when hijackers flew two commercial airplanes into the Twin Towers. The 104-story, $3.9 billion skyscraper arose out of those ashes and now dominates the New York City skyline as a symbol of the resurgence of Lower Manhattan.

While the first 175 Condé Nast employees moved in on Monday, over the next several months, around 3,500 people who work for the publishing giant will move into office space that will occupy floors 20 through 44 of the building. One World Trade Center is currently 60 percent leased. Other tenants thus far include advertising firm Kids Creative, stadium operator Legends Hospitality, the BMB Group investment adviser, Servcorp, a provider of executive offices, trade and cultural facility China Center and the federal government’s General Services Administration (GSA). The observation deck on the 102nd floor will open to the public this spring.

“Condé Nast is proud to be a part of this important moment of renewal for the city of New York,” said Condé Nast spokeswoman Patti Rockenwagner. “We are excited about contributing to the vitality of this community for years to come.”

Authorities say the building will be one of the safest in the world. Patrick Foye, executive director of the Port Authority of New York and New Jersey, called One World Trade Center “the most secure office building in America.” The building is protected with steel-reinforced concrete and design firm Skidmore, Owings & Merrill included many other safety features to better prepare the skyscraper for an accident or terrorist attack.
