Preview The 9/11 Memorial Museum : Inside WTC Ground Zero

(WTC) complex consisted of seven buildings, spanning 16 acres. The complex housed office space, an observation deck, the "Windows on the World" restaurant, and an underground shopping mall, and served as a transit hub for New Jersey PATH train and New York City subway riders. Approximately 50,000 people worked at the WTC, with another 40,000 passing through daily.



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, Pa., and at the Pentagon, as well as the six people killed in the World Trade Center bombing in February 1993.

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 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.
