What makes National September 11 Memorial & Museum historically important?
Situated on the eight-acre World Trade Center site in Lower Manhattan, the National September 11 Memorial & Museum stands as the principal tribute to the 2,977 people killed in the terror attacks of September 11, 2001, and the six victims of the 1993 World Trade Center bombing. The outdoor memorial, designed by architect Michael Arad and landscape architect Peter Walker, features two enormous reflecting pools set within the footprints of the original Twin Towers, each nearly an acre in size with the largest man-made waterfalls in North America cascading thirty feet into their voids. Bronze parapets encircling each pool bear the names of every person who perished, arranged not alphabetically but by meaningful adjacency so colleagues, friends, and family members rest side by side for eternity. Below the plaza, the museum descends seventy feet underground to bedrock, where artifacts, oral histories, and exposed slurry wall foundations tell the story of that day and its lasting impact on New York City, the United States, and the world.
