• The World Trade Center twin towers were located in Lower Manhattan, New York City, and were completed in 1973. They were the tallest buildings in the world until 1974 when the Sears Tower in Chicago was completed.
• Each tower was 110 stories tall and had a height of 1,368 feet (417 meters). The towers had a square footprint of 208 feet (63.4 meters) on each side.
• The towers were part of a larger complex that included seven buildings, including the Marriott World Trade Center, which was also destroyed in the 9/11 attacks.
• The towers had a total floor area of 10.4 million square feet (966,000 square meters) and could accommodate up to 50,000 workers and visitors each day.
• The construction of the towers required a total of 200,000 tons of steel, 425,000 cubic yards of concrete, and 43,600 windows.
• The towers were designed to withstand the impact of a Boeing 707 airplane, which was the largest commercial aircraft in service at the time of their construction. However, they were unable to withstand the impact of the Boeing 767 airplanes that were flown into them on September 11, 2001, by terrorists.

Overall, the World Trade Center twin towers were a symbol of American strength, resilience, and innovation. Their destruction in the 9/11 attacks was a tragedy that shook the world and led to significant changes in global politics and security.
