Designed by architect Michael Arad and landscape architect Peter Walker, the Memorial honors the nearly 3,000 victims of the terrorist attacks of both 1993 and 2001 by creating a meditative space of nearly 400 trees in clustered formation broken up by two large recessed pools. Set within the footprints of the Twin Towers, the 8-acre Memorial Plaza serves to remember the lives lost by inscribing their names alongside the largest manmade waterfalls in the country.
