The 9/11 Memorial is located at the site of the former World Trade Center complex and occupies approximately half of the 16-acre site. The 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. More than 400 trees surround the reflecting pools. Its design conveys a spirit of hope and renewal, and creates a contemplative space separate from the usual sights and sounds of a bustling metropolis.
Swamp white oak trees create a rustling canopy of leaves over the plaza. This grove of trees brings green rebirth in the spring, provides cooling shade in the summer and shows seasonal color in fall. A small clearing in the grove, known as the Memorial Glade, designates a space for gatherings and special ceremonies.
