WTC New York

The original World Trade Center was a complex with seven buildings featuring landmark twin towers in Lower Manhattan, New York City, United States. The complex opened on April 4, 1973, and was destroyed in 2001 during the September 11 attacks. The site is being rebuilt with five new skyscrapers and a memorial to the casualties of the attacks. As of November 2011^[update], only one skyscraper has been completed, with four more expected to be completed before 2020. One World Trade Center will be the lead building for the new complex; reaching 100 stories and becoming the tallest building in New York City during April 2012, it is expected to be finished by 2013. A sixth tower is still awaiting confirmation to be built.

At the time of their completion, the original 1 World Trade Center (the North Tower) and 2 World Trade Center (the South Tower), known collectively as the Twin Towers, were the tallest buildings in the world. The other buildings included 3 WTC (the Marriott World Trade Center), 4 WTC, 5 WTC, 6 WTC (which housed United States Customs), and 7 WTC. All of these buildings were built between 1975 and 1985.
