List of tenants in 2 World Trade Center

The original 2 World Trade Center (also known as the South Tower, Tower 2, Building Two, or 2 WTC) was one of the Twin Towers in the original World Trade Center in New York City. The Tower was completed and opened in 1973 at a height of 415 meters (1,362 ft) to the roof, distinguishable from its twin, the North Tower, by its outdoor observation deck and the absence of a television antenna. Both the South Tower and the North Tower had mechanical floors, and the same type of walls. On the 107th floor of this building was a popular tourist attraction called "Top of the World Trade Center Observatories," and on the roof was an observation deck accessible to the public and a disused helipad at the center. The address of this building was 2 World Trade Center with the WTC complex having its own ZIP code of 10048.

2 World Trade Center was destroyed along with the North Tower (1 World Trade Center) in the September 11 attacks. The South Tower was the second tower to be struck by a hijacked aircraft at 9:03 a.m., and the first tower to collapse, at 9:59 a.m. The South Tower stood for 56 minutes after the aircraft impact. Of the 2,977 victims killed in the attacks, 900 were in the South Tower and on the ground.

The new 2 World Trade Center, which is currently on hold, has a diagonally-pointed roof, with no observation deck, and no mechanical floors. At the National September 11 Memorial & Museum, the southern pool marks the spot where the South Tower stood.
