World Trade Center (1973–2001)

World Trade Center (1973–2001). The original World Trade Center was a large complex of seven buildings in the Financial District of Lower Manhattan, New York City. It opened on April 4, 1973, and was best known for its iconic twin towers, which were the tallest buildings in the world from 1971 until the completion of the Sears Tower in 1973. The complex became a global symbol of New York City and American economic power before its destruction in the September 11 attacks.

History and construction

The concept for a world trade center in New York City was championed in the late 1950s by David Rockefeller and backed by his brother, New York Governor Nelson Rockefeller. The Port Authority of New York and New Jersey was selected to oversee the massive project, acquiring the site in Radio Row, a vibrant electronics district. Construction began in August 1966 under the leadership of Port Authority executive director Austin J. Tobin, with Tishman Realty & Construction as the main contractor. The north tower, 1 World Trade Center, was completed in December 1970, and its twin, 2 World Trade Center, finished in July 1971, with the entire complex officially opening in April 1973. The project faced significant financial and logistical challenges but was seen as a catalyst for the revitalization of Lower Manhattan.

Design and architecture

The design was led by architect Minoru Yamasaki and the firm Emery Roth & Sons, with Leslie E. Robertson serving as the structural engineer. The twin towers each rose 110 stories, utilizing an innovative structural system of closely spaced exterior steel columns and a lightweight core, which maximized office space. The towers' facades were clad in aluminum alloy and featured narrow windows. The complex also included the Marriott World Trade Center hotel, 4, 5, and 6 World Trade Center, and the Austin J. Tobin Plaza. The underground Mall at the World Trade Center was one of the largest commercial shopping centers in Manhattan.

Major events and incidents

The complex was the site of several significant events prior to 2001. In February 1974, a protest by Philippe Petit resulted in his famous high-wire walk between the towers. A major fire broke out in 1 World Trade Center on February 13, 1975. The center was the target of a terrorist attack on February 26, 1993, when a truck bomb planted by Ramzi Yousef and others detonated in the underground garage, killing six people. The 1998 plot by Osama bin Laden and Khalid Sheikh Mohammed to destroy the towers with hijacked airliners was a direct precursor to the later attacks.

Cultural impact

The World Trade Center quickly became an indelible part of the New York City skyline and a global cultural icon. It was featured prominently in countless films, including *King Kong* (1976) and *Home Alone 2: Lost in New York*, and television shows. The towers were a popular tourist destination, with observation decks atop 2 World Trade Center and the Windows on the World restaurant on the top floors of 1 World Trade Center. They symbolized modernity and ambition, often serving as a backdrop for major events like the Liberty Weekend celebrations in 1986 and the 1998 Goodwill Games opening ceremony.

Destruction in the September 11 attacks

On the morning of September 11, 2001, al-Qaeda terrorists hijacked four commercial airliners. At 8:46 a.m., American Airlines Flight 11 was deliberately crashed into the north facade of 1 World Trade Center. At 9:03 a.m., United Airlines Flight 175 struck 2 World Trade Center. The impacts and resulting fires caused catastrophic structural damage. At 9:59 a.m., 2 World Trade Center collapsed, followed by 1 World Trade Center at 10:28 a.m. The debris and subsequent fires led to the partial or complete destruction of all other buildings in the complex, including 7 World Trade Center, which collapsed that evening. The attacks resulted in the deaths of 2,606 people at the World Trade Center site, along with 147 on the two planes. The site became known as Ground Zero and is now home to the National September 11 Memorial & Museum and the new One World Trade Center skyscraper.
