40s
In 1946, New York State Legislature created the World Trade Corporation to develop the proposed World Trade Center.
The original proposal was for only one 70-story building in Downtown Manhattan, not the final twin towers design. Winthrop Aldrich, chairman of Chase Bank, was appointed to explore the project’s feasibility. The New York State Legislature passed a bill authorizing Governor Thomas E. Dewey to move forward with development.
50s
The World Trade Corporation nominated one of the nation’s premier architectural firms, Skidmore, Owings, and Merrill (SOM) to develop a plan for a “new Lower Manhattan” in 1958.
SOM proposed a complete rebuilding and expansion of the Financial District and suggested building a World Trade Center. In 1958, Chase Manhattan Bank vice chair David Rockefeller announced plans to build a multi-million-square-foot complex on Lower Manhattan’s east side. The Port Authority of New York and New Jersey (PANYNJ) agreed to oversee the project. Although many questioned the Port Authority’s entry into the real estate market, Austin J. Tobin, Executive Director of the PANYNJ saw the project as a way to enhance the agency’s power and prestige.

September 20, 1962: The Port Authority chose the current site for the World Trade Center.
Minoru Yamasaki was selected to design the project. Less than two years and more than 100 design concepts later, the Port Authority unveiled the $525 million World Trade Center plan to the public. It was a composite of six buildings comprised of 10 million square feet of office space. At its core were the Twin Towers, which at 110 stories (1,368 and 1,362 feet) would be the world’s tallest skyscrapers.

January 18, 1964
Yamasaki’s design for the World Trade Center was unveiled to the public.
The design consisted of a square plan approximately 207 feet in dimension on each side. The buildings were designed with narrow office windows 18 inches wide, due to Yamasaki’s fear of heights and his desire to make building tenants feel secure. The building facades were covered in aluminium-alloy.

December 23, 1970: the topping out ceremony of the North Tower.
The first tenants moved into the north tower, 1 WTC, although the tower was not fully completed until 1972. 1 WTC featured many innovations masterminded by Yamasaki and his team. Among them were the Twin Towers’ high-speed elevators, sky lobbies, and “hollow tube” building model that distributed weight from the inner core across floor trusses to the exterior’s closely spaced steel columns. The load-bearing exterior also served to brace against wind. Some of the major tenants at 1 WTC included Marsh USA INC, Bank of America, Cantor Fitzgerald Securities, and Brown & Wood LLP.

The Twin Towers debuts as the tallest buildings in the world.
The Twin Towers debut as the tallest buildings in the world -at 1,368 and 1,362 feet and 110 stories each– surpassing the height of the Empire State Building until the Sears Tower in Chicago, providing 10 million sq ft of office space was built. The ceremonial opening of the Twin Towers on this date marked seven years of construction, preceded by more than a decade’s worth of planning that transformed 16 acres of Lower Manhattan into an international business hub. In addition to the Twin Towers, four smaller buildings and a hotel, all built nearby around a central landscaped plaza, completed the complex.
The mall at the World Trade Center, which was located immediately below the plaza, was the largest shopping mall in Lower Manhattan. The six basements housed two subway stations and a stop on the PATH trains to New Jersey. Some 50,000 people worked in the buildings, while another 200,000 visited or passed through each day.
August 7, 1974
Philippe Petit completed a high-wire walk between the Twin Towers.
After six years of planning and research, the 24-year-old Petit made a total of eight total crossings between the mostly finished towers, a quarter mile above the sidewalks of Manhattan, in an unexpected event that lasted about 45 minutes. Philippe Petit’s high-wire walk is credited with bringing much needed popular attention and fondness to the Twin Towers.

A fire broke out in the North Tower.
A fire broke out on the 11th floor of the North Tower. The fire then spread from the 9th to 14th floors by igniting the insulation of telephone cables in a utility shaft that ran between the floors. Most of the damage was concentrated on the 11th floor. Fireproofing protected the steel from melting and there was no structural damage to the tower.

The 610-foot Seven WTC was designed by Emery Roth & Sons with a red granite façade and a trapezoidal footprint. To supply power to the 10048 zip code, which was dedicated solely to the WTC site, Con Edison built an electrical substation located below Seven WTC in 1967. Tishman Realty & Construction managed construction of the building, which began in 1983. Some of the major tenants at Seven WTC were Salomon Smith Barney, American Express Bank International, ITT Hartford Insurance Group and Standard Chartered Bank.

1990s
A van loaded with 1,500 pounds of explosives was planted by a group of terrorists in an underground parking garage of the north tower.
Their goal was to knock the North Tower into the South Tower, bringing both towers down and killing thousands of people. The attack killed six people, including a pregnant woman, injured more than 1,000 people and created a five-story hole beneath the towers, resulting in hundreds of millions of dollars of damage.

1 WTC plans were unveiled to the public.
The shimmering skyscraper of glass, steel, and cable would stand at 1,776 feet, invoking the symbolism of the building. The building was designed to sit at the northwest corner of the site. The design also called for 70 commercial stories with 2.6 million square feet of office space, plus an underground regional transportation hub, garages, and several shopping centers. A public observation deck and a rebuilt Windows on the World, the restaurant that once sat atop the north tower was also in the plan. The previous World Trade Center buildings each had 110 stories, but 1 World Trade Center will rise higher because of a large glass structure and 276-foot spire topping off the building.

Santiago Calatrava presented the design for the WTC Transportation Hub at the Winter Garden.
The design evokes the image of a bird in flight and incorporates steel, glass, and light. To bring an even greater sense of open air and natural light to the station’s concourse, mezzanine, and platform levels, Calatrava designed the hub’s ceiling to retract-an innovative concept used mostly in sports arenas. Each level inside the station was designed to be column-free to create an open, bright space. Through this Transportation Hub, pedestrians will have access to Hudson River ferry terminals, PATH trains, 13 subway lines, and possibly a direct rail link to JFK International Airport. The Hub will be positioned at the northeast corner of the WTC site at Church and Vessey Streets and is expected to form an underground connection between the World Financial Center and the Metropolitan Transportation Authority’s Fulton Street Transit Center.
