List of tenants in Two World Trade Center

The South Tower (also known as Tower 2, Building Two or 2 WTC) of the World Trade Center in New York City was completed and opened in 1973 at a height of 415 meters (1,362 ft), distinguishable from the North Tower by its outdoor observation deck and the absence of a television antenna. The address of this building was 2 World Trade Center with the WTC complex having its own ZIP code of 10048. It 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 at 9:03 AM and the first tower to collapse at 9:59 AM.

On the 107th floor of this building was a popular tourist attraction called Top of the World Trade Center Observatories. On the roof was an observation deck accessible to the public and a disused helipad at the center.
