The National September 11 Memorial and Museum commemorates the approximately 3,000 lives lost in the 2001 terrorist attack that destroyed the twin towers of the World Trade Center. There are two square pools where the World Trade towers once existed, with trees and some green spaces around them. The names of all the victims are written on the walls that are near these pools. The memorial opened on September 12th, 2011.
