Narrated by Carol Willis, Founder & Director for the Skyscraper Museum
The National September 11th Memorial, which includes the waterfall reflecting pools that mark the footprints of the Twin Towers, the 9/11 Museum, and the landscaped plaza encompass eight of the sixteen acres of the original, and now rebuilt, World Trade Center site. On the other eight acres, ultimately five skyscrapers will replace the ten million square feet of office space in the destroyed Twin Towers. To date, three office buildings have been completed; One, Three, and Four World Trade Center.
