What Were the Trade Centers Used For?
The World Trade Center was a large office complex in lower Manhattan, New York City. The complex consisted of seven buildings, including the twin towers, and was the headquarters of the Port Authority of New York and New Jersey.
The Trade Center was also a popular tourist destination, with the observation deck of the South Tower being the second most popular tourist attraction in New York City, after the Empire State Building.
The complex was destroyed in the terrorist attacks of September 11, 2001, when two hijacked planes crashed into the twin towers.
The attacks killed 2,606 people in the towers and in the surrounding area, and also caused the collapse of the South Tower.
The World Trade Center was rebuilt following the attacks, with the new One World Trade Center being the tallest building in the United States.
