List of tenants in One World Trade Center



The North Tower (also known as Tower 1, Building One or 1 WTC) was one of the twin towers of the original World Trade Center in New York City. It was opened in 1970 and completed in 1972, standing at a height of 417 m (1,368 ft). It was distinguishable from its twin, the South Tower, by the 360-foot-tall (109-m) telecommunications antenna on its roof. The address of this building was 1 World Trade Center, with the WTC complex having its own ZIP code of 10048. The tower was destroyed, along with the South Tower, in the September 11 terrorist attacks in 2001.

The North Tower was the first tower to be struck by a hijacked aircraft during the attacks, with American Airlines Flight 11 impacting at 8:46 a.m. EDT. It was the second tower to collapse, at 10:28 a.m. Nobody in the 92nd floor or above survived the tower's collapse. Following its completion in 1972, the North Tower was the tallest building in the world for two years, until its height was surpassed by the Sears Tower. Throughout its existence, its record number of floors was not surpassed by any other building, although it was matched by its twin. In 2009, eight years after the North Tower's destruction, the Burj Khalifa in Dubai became the first tower to exceed its floor count of 110.
