Narrated by Carol Willis, Founder & Director for the Skyscraper Museum
One World Trade Center is a skyscraper invested with many meanings. Its presence as the dominant tower at the complex at once marks the rebuilding at Ground Zero, and, according to its architect David Childs of Skidmore, Owings & Merrill, creates a memorial on the skyline that echoes the memorial in the ground. The roof height is the same as that of the North Tower of the original World Trade Center, while the spire rises to 1,776 feet to refer symbolically to the year of American independence.
