World Trade Center History:
The World Trade Center in New York City was a complex of seven buildings, mostly designed by Japanese American
architect Minoru Yamasaki and developed by the Port Authority of New York and New Jersey. It was initiated by a
Lower Manhattan Association created and chaired by David Rockefeller, along with strong backing from the then New
York governor, his brother, Nelson Rockefeller. Larry Silverstein held the most recent lease to the complex, the
Port Authority having leased it to him in July of 2001. The complex, located in the heart of New York City's downtown
financial district, contained 13.4 million square feet of office space, almost four percent of Manhattan's entire
In 1966, construction of the World Trade Center began with a groundbreaking that razed 13 square blocks of low
rise buildings, some of which predated the US Civil War. In 1970, construction was completed on One World Trade
Center, with its first tenants moving into the building in December 1970. Tenants first moved into Two World Trade
Center in January 1972. Initially conceived as a complex dedicated to companies and organizations directly involved
in "world trade," they at first failed to attract the anticipated clientele; during the WTC's early years
various governmental organizations became key tenants. It was not until the 1980s, as New York's economy improved,
that an increasing number of private companies — mostly financial firms tied to Wall Street — became tenants.
On any given day, some 50,000 people worked in the towers with another 200,000 passing through as visitors. The
complex was so large that it had its own ZIP Code: 10048
French high wire artist Philippe Petit walked between the towers on a tightrope in 1974, and Brooklyn toymaker
George Willig scaled the south tower in 1977.
On February 13, 1975, the WTC North Tower was beset by a fire, which "burned at temperatures in excess of
700°C (1,292°F) for over three hours and spread over some 65 percent of the 11th floor, including the core,
caused no serious structural damage to the steel structure" (New
York Times, Saturday 15th February 1975)
On February 26, 1993 at 12:17 PM, a Ryder truck filled with 1,500 pounds (682 kg) of explosives was planted by
Ramzi Yousef and detonated in the underground garage of the North Tower, opening a 100 foot (30 m) hole through
4 sublevels of concrete. Six people were killed and over a thousand injured.
Many people inside the North Tower were forced to walk down darkened stairwells which contained no emergency lighting,
some taking two hours or more to reach safety. As the Port Authority was a bi-state agency, the towers were exempt
from New York City building codes. Subsequent to the bombing The Port Authority installed emergency lighting in
the stairwells. It is believed that this lighting saved many lives during the events of September 11, 2001. As
a memorial to the victims of the bombing of the tower, a reflecting pool was installed with the names of those
who had been killed in the blast. Following the September 11, 2001 attacks, relief workers found a single fractured
piece of this fountain; to date it is the only remaining part of the 1993 memorial that survived the collapse of
One of the world's largest gold depositories was stored underneath the World Trade Center, owned by a group of
commercial banks. The 1993 bomb detonated close to the vault, but it withstood the explosion, as did the towers.
Best known for its iconic 110-story Twin Towers, all of the original buildings in the complex were destroyed in
the September 11, 2001 attacks: 1 WTC, 2 WTC (North and South Towers) and 7 WTC collapsed; 3 WTC (Marriott Hotel)
was crushed by the collapses of 1 WTC and 2 WTC; and 4 WTC, 5 WTC, and 6 WTC were damaged beyond repair and later
Ultimately, 2,749 death certificates were filed relating to the WTC attacks, as of February 2005.
13 people died
after the disaster, from injuries received on September 11; three of these people died in Massachusetts, Missouri,
and New Jersey, and the rest died in New York.
