The National September 11 Memorial is a tribute of remembrance and honor to the nearly 3,000 people killed in the terror attacks of September 11, 2001 at the World Trade Center site, near Shanksville, Pennsylvania, and at the Pentagon in Washington, DC, as well as the six people killed in the World Trade Center bombing in February 1993.

The memorial opened on the tenth anniversary of the attacks, for family members of victims. The public may visit with reserved timed tickets.  A plan for a museum is still in the works.

The memorial’s twin reflecting pools are each nearly an acre in size and feature the largest manmade waterfalls in the North America. The pools sit within the footprints where the World Trade Center's Twin Towers once stood. Architect Michael Arad and landscape architect Peter Walker created the memorial design selected from a global design competition that included more than 5,200 entries from 63 nations.

The names of every person who died in the 2001 and 1993 attacks are inscribed into bronze panels edging the memorial pools, a powerful reminder of the largest loss of life resulting from a foreign attack on American soil and the greatest single loss of rescue personnel in American history.

Advance visitor passes to the 9/11 Memorial are required. Visitors must reserve advance passes for a specific date and time. Visitor passes are free and available through the memorial's online reservation system.  The online system is highly recommended;  if you need reservation assistance for any reason, call (212) 266-5200.
