9/11 Ground Zero Tour
This is the principal memorial commemorating the 9/11 attacks of 2001 and 1993 WTC bombing. It is located at the site of the former Twin Towers that were destroyed. The 9/11 Memorial features two enormous waterfalls and reflecting pools, each about an acre in size, set within the footprints of the original twin towers. The Memorial Plaza is one of the most eco-friendly plazas ever constructed.
