One World Trade Center (1 World Trade Center), more simply known as 1 WTC and formerly known as the Freedom Tower, is the lead building of the new World Trade Center complex in Lower Manhattan in New York City. The 110-story supertall skyscraper is being constructed in the northwest corner of the World Trade Center site, occupying the location where the original 8-story 6 World Trade Center once stood. The north side of the tower runs between the intersection of Vesey and West streets on the northwest and the intersection of Vesey and Washington streets on the northeast, with the site of the original North Tower/1 WTC offset to the south. Construction on below-ground utility relocations, footings, and foundations for the building began on April 27, 2006. On March 30, 2009, the Port Authority confirmed that the building would be known by its legal name of One World Trade Center, rather than the colloquial name, Freedom Tower. Upon its completion in 2013, One World Trade Center will be the tallest building in the United States and one of the tallest in the world, with its radio antenna reaching a symbolic height of 1,776 feet (541.3 m) in reference to the year of American independence.
Along with One World Trade Center, the new World Trade Center site will feature three other high-rise office buildings, located along Greenwich Street, and the National September 11 Memorial & Museum, located at the foot of One World Trade Center. The construction is part of an effort to memorialize and rebuild the original World Trade Center complex, which was destroyed during the terrorist attacks of September 11, 2001.
