Top 10 Facts about world trade center 9/11

The World Trade Center was a complex of seven buildings in Lower Manhattan, New York City, including the famous Twin Towers. The construction of the World Trade Center began in 1966 and was completed in 1973. The Twin Towers were the tallest buildings in the world when they were completed, standing at 1,368 and 1,362 feet tall. The World Trade Center was owned and operated by the Port Authority of New York and New Jersey. The complex was a major center for international trade and finance, with over 430 companies from 28 countries having offices there. On September 11, 2001, terrorists affiliated with al-Qaeda hijacked four commercial airplanes, two of which were flown into the Twin Towers, causing them to collapse. The attacks on the World Trade Center resulted in the deaths of nearly 3,000 people and caused billions of dollars in damage. The World Trade Center was rebuilt after the attacks, with a new One World Trade Center building opening in 2014. The site also includes a memorial and museum to commemorate the victims of the September 11 attacks. The redevelopment of the World Trade Center site has involved multiple architects, planners, and developers, and is one of the largest and most complex urban redevelopment projects in history.
