1 World Trade Center (1970–2001)
The original One World Trade Center (also known as the North Tower, Tower 1, Building One, or 1 WTC) was one of the Twin Towers of the original World Trade Center complex in New York City. It was completed in 1972, stood at a height of 1,368 feet (417.0 m), and was the tallest building in the world until 1973, when surpassed by the Sears Tower in Chicago. On the 106th and 107th floors of this building were a complex of dining, meeting, and entertainment venues known as Windows on the World.
It was distinguishable from its twin, the original 2 World Trade Center, also known as the South Tower, by the 360-foot (110 m) telecommunications antenna on its roof. Including the antenna, the building stood at a total height of 1,728 feet (526.7 m). The North Tower was 6 feet taller than the South Tower because floor 43 was 2 feet taller and floor 67 was 4 feet taller than the standard ceiling of 12 feet. These two floors were used by the Port Authority. Other things that made the North Tower distinguishable from its twin was a canopy connected to the North Tower's west facade on street level as well as two pedestrian walkways that extended from the west and south promenades of Three and Six World Trade Center to the North Tower's north and south facades on plaza level, all of which the South Tower lacked. The building's address was 1 World Trade Center, and the WTC complex had its own ZIP code (10048) due to its large size.
The original World Trade Center was destroyed in the terrorist attacks of September 11, 2001. Struck by American Airlines Flight 11 at 8:46 a.m., the North Tower was the first of the Twin Towers to be hit by a hijacked aircraft, and the second to collapse, at 10:28 a.m. The North Tower stood for 102 minutes after the aircraft impact. Of the 2,977 victims killed in the attacks, around 1,700 were in the North Tower or on the ground.
The North Tower was succeeded by the present-day One World Trade Center tower, which was opened in November 2014 as the lead building of the redeveloped World Trade Center site. At the National September 11 Memorial & Museum, the northern pool marks the spot where the North Tower once stood.
In 1961, the Port Authority of New York and New Jersey agreed to build the World Trade Center on the site of the Hudson Terminal in Lower Manhattan, New York City. On September 20, 1962, the Port Authority announced the selection of Minoru Yamasaki as lead architect and Emery Roth & Sons as associate architects. Yamasaki devised the plan to incorporate twin towers. His original plan called for the towers to be 80 stories tall, but to meet the Port Authority's requirement for 10,000,000 square feet (930,000 m2) of office space, the buildings would each have to be 110 stories tall. Yamasaki's design for the World Trade Center, unveiled to the public on January 18, 1964, called for a square plan approximately 208 feet (63 m) in dimension on each side.
In March 1965, the Port Authority began acquiring property at the World Trade Center site. Demolition work began on March 21, 1966, and groundbreaking for the construction of the World Trade Center took place on August 5, 1966. In January 1967, the Port Authority awarded $74 million in contracts to various steel suppliers. Construction work began on the North Tower in August 1968. The topping out ceremony for 1 WTC (the North Tower) took place on December 23, 1970. The first tenants moved into the North Tower on December 15, 1970, while it was still under construction, and a ribbon cutting ceremony took place on April 4, 1973.
On the 106th and 107th floors of this building were a complex of dining, meeting, and entertainment venues known as Windows on the World.
On February 12, 1975, a three-alarm fire broke out on the North Tower's 11th floor, spreading to the 9th and 14th floors. At that time, the World Trade Center had no fire sprinkler systems. A disgruntled custodian was discovered to have deliberately started the fire and was criminally charged. Following the fire, in 1981, the Port Authority announced a $45 million plan to install sprinklers throughout the World Trade Center.
