Freedom Tower

1 World Trade Center, also known by its nickname and former name Freedom Tower, is the main building of the new World Trade Center under construction in Lower Manhattan in New York City, USA. The tower will be located in the northwest corner of the 16-acre World Trade Center site, bound by Vesey, West, Washington and Fulton streets. Construction on below-ground utility relocations, footings, and foundations for the 1,776-foot building began on April 27, 2006. On December 19, 2006, the first steel columns were installed in the building's foundation. Three other high-rise office buildings are planned for the site along Greenwich Street, and they will surround the World Trade Center Memorial, which is under construction. The area will also be home to a museum dedicated to the history of the site. On March 26, 2009, the Port Authority said that the building will be known as 'One World Trade Center,' replacing its former name 'Freedom Tower.' When completed, 1 World Trade Center will be the tallest building in the United States as well as one of the tallest in the world. It will also stand as the tallest all-office building in the world.
