One World Trade Center (also 1 World Trade Center or 1 WTC, dubbed the Freedom Tower during initial basework) is the primary building of the new World Trade Center complex in Lower Manhattan, New York City, and the tallest skyscraper in the Western Hemisphere.
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.
