One World Trade Center , abbreviated as 1 WTC and commonly known by its previous name Freedom Tower, is the lead building of the new World Trade Center complex in Lower Manhattan, New York City.
The 104-story supertall skyscraper is being constructed in the northwest corner of the 16-acre World Trade Center site, occupying the location where the original 8-story 6 World Trade Center once stood. The building is bounded to the west by West Street, to the north by Vesey Street, to the south by Fulton Street, and to the east by Washington Street.
Construction on below-ground utility relocations, footings, and foundations for the building began on April 27, 2006.
The tower's steel structure topped-out on August 30, 2012, and work is currently underway on its spire. At the time of its completion (check out the rendering) in 2013, One World Trade Center will be the tallest building in the Western Hemisphere and the third-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in reference to the year of American independence. It has been the tallest building in New York City since April 30, 2012.
On March 30, 2009, the Port Authority of New York and New Jersey confirmed that the building would be known by its legal name of One World Trade Center, rather than the colloquial name, Freedom Tower.
The new World Trade Center complex will also feature three other high-rise office buildings, located along Greenwich Street, and the National September 11 Memorial & Museum, located just south of One World Trade Center, where the Twin Towers once stood. The construction is part of an effort to memorialize and rebuild following the destruction of the original World Trade Center complex during the terror attacks of September 11, 2001.
