April 4

The World Trade Center in New York is officially dedicated on 4 April  

The World Trade Center is a complex of various buildings in Lower Manhattan, New York City, United States, replacing an earlier complex with the same name on the same site. The original World Trade Center was a complex of seven buildings. It featured landmark twin towers, which opened on April 4, 1973 and were destroyed in the September 11 attacks of 2001, along with 7 World Trade Center. The other buildings in the complex were damaged in the attacks, and their ruins were eventually demolished. The site is being rebuilt with five new skyscrapers and a memorial to the casualties of the attacks. As of November 2011, only one skyscraper has been completed; the other four are expected to be completed before 2020. One World Trade Center will be the lead building for the new complex, reaching more than 100 stories at its completion.[2] It became the tallest building in New York City on April 30, 2012, and is expected to be finished by 2013. A sixth tower is awaiting confirmation.
