National September 11 Memorial
Also called: 9/11 Memorial, Reflecting Absence
On 11 September 2011, the tenth anniversary, two memorial pools opened in the footprints of the fallen towers, with the names of 2,983 people inscribed in bronze around them. In 2014 the new One World Trade Center opened beside them.

The memorial leaves the footprints of the two towers empty and sets in each a square pool of nearly an acre. Water pours down the four walls and disappears into a deeper void at the centre. Designed by the Israeli-American architect Michael Arad, it is called “Reflecting Absence”.
Bronze parapets around the pools carry the names of the 2,983 people killed on 11 September 2001 and in the 1993 World Trade Center bombing. They are arranged not alphabetically but so that people who worked together, flew together or asked to be near one another stand side by side.
In November 2014 the new One World Trade Center opened beside them, its height of 1,776 feet (541 m) recalling the year of American independence.
