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’s twin reflecting pools are each nearly an acre in size and feature the largest man-made waterfalls in North America.

The nearly 3,000 names of the men, women, and children killed in the attacks of September 11, 2001 and February 26, 1993 are inscribed on bronze parapets surrounding the twin memorial pools. See a full list of the names on the Memorial.

This dedicated space honors the ongoing sacrifice of rescue, recovery, and relief workers, and the survivors and members of the broader lower Manhattan community, who are sick or have died from exposure to toxins at the World Trade Center site in the aftermath of 9/11. It also recognizes the courage, selflessness, and perseverance of the men and women of the rescue and recovery effort.

A Callery pear tree became known as the “Survivor Tree” after enduring the September 11, 2001 terror attacks at the World Trade Center.

Each year in commemoration of 9/11, the twin beams of Tribute in Light shine, recalling the Twin Towers and honoring those killed.

Each weeknight, 9/11 Memorial staff climb inside the twin pools of the Memorial to give them a top-to-bottom cleaning. Watch as Chief Engineer Anthony LoCasto gives a behind-the-scenes tour of all the care that goes into keeping the Memorial a special place for reflection.
