The World Trade Center in Lower Manhattan combines the One World Trade Center observatory with the 9/11 Memorial. From the observatory, visitors see Manhattan views that shift between day, sunset, and night, then continue to the 9/11 Memorial and Museum. At the observatory entrance, visitors pass through security and take an elevator up, with video and screen presentations shown before entry. The memorial's two reflecting pools sit in the footprints of the former Twin Towers and are inscribed with the names of the victims.
