The tower on the right was 2 World Trade Center. The WTC complex's seven buildings are all partially visible. The original 7 World Trade Center was the red granite-clad structure to the left of the Twin Towers. The East River may be seen in the backdrop. Height record The Empire State Building preceded [I] from 1970 to 1973. Willis Tower has surpassed it. The Chicago skyscraper is 828 feet tall.
Willis Tower was built from 1983 to 1994. It stands 50 stories high and was at the time of its completion the tallest building in the Western Hemisphere. The Sears Tower in Chicago is now the world's second-tallest building. Tokyo's 23rd Century Museum of Contemporary Art, which opened in 2003, is now the world's third-tallest building. The Petronas Twin Towers in Kuala Lumpur, Malaysia, are currently the highest buildings in the world. They are 638 feet tall.
The World Trade Center complex was designed by Skidmore, Owings & Merrill with John Burgee as chief architect. Its construction was managed by Silverstein Properties through Parsons Brinckerhoff. When completed in February 1974, the 1,776-foot-high Twin Towers were the tallest structures in New York City. They remained so for three years until the Empire State Building was finally topped out in April 1977.
In June 1998, an airplane hijacked by terrorists crashed into the Twin Towers, killing approximately 3,000 people. The impact destroyed any hope of finding survivors inside the wreckage.
The North Tower The Twin Towers—the original 1 World Trade Center (the North Tower), at 1,368 feet (417 m), and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m)—were the highest structures in the world at the time of their construction. (1973-2001) The World Trade Center (WTC)

Tower 1 was the highest building in the world until it was destroyed on 9/11, with a height of 1,741 feet to the top of the antenna. The first World Trade Center twin towers were flat-topped and somewhat varied in height. The original plan called for the replacement tower to be 440 feet taller than Tower 1.
The current World Trade Center towers are 1,776 feet high, including their antennas. They were built by Condé Nast which owned the buildings before they were acquired by New York City-based developers Silverstein Properties and Vornado Realty Trust in July 2006 and April 2009 respectively. The buildings' cost exceeded $1 billion.
On September 11, 2001, two airplanes crashed into the Twin Towers killing2,971 people. A third plane hit the Pentagon, also killing 119 people. All three attacks were committed by terrorists who wanted to stop the war in Iraq and kill as many Americans as possible. This massacre served as a catalyst for changes that led to the creation of the Department of Homeland Security.
After 9/11, the Federal Aviation Administration (FAA) required all commercial aircraft to have passenger identification devices called "smart cards" or "enhanced passenger lists". These cards contain information about each person aboard the flight including full names, dates of birth, and passport numbers.
World Trade Center No. 1. One World Trade Center in New York City has been the tallest building in the United States since it was completed in 2013. Its height makes it the second-tallest free-standing building in the country after The Trump Tower in Chicago. WTC No. 2 now stands as the tallest building in Hudson Yards, a business district in Manhattan's West Side.
WTC was built by the Port Authority of New York and New Jersey, which operates both the port and the transit system known as PATH. It was designed by David Childs and Peter Kiewitt, with structural engineering by Skidmore, Owings & Merrill. The building was opened on February 4, 1970, by New York Governor Nelson Rockefeller. It was the first major skyscraper built after the assassination of John F. Kennedy, when public fear of further attacks prompted architects to design more secure buildings.
WTC stood for nearly 40 years until 1972, when the IBM Building in New York City reached 1,003 feet (305 m). It was not completed until several months after the 9/11 attacks, but its height made it an ideal target for terrorists who sought to destroy property rather than people.
