The 110,000-foot space preserves the story of 9/11 through multimedia displays, archives, narratives, and a collection of monumental and personal artifacts. It has two core exhibitions. The historical exhibition, which explores what happened on 9/11, what led up to the attacks, and how 9/11 continues to shape our world, and the memorial exhibition that commemorates victims’ lives.
The national tribute honors the 2,983 people who were killed in the terrorist attacks of September 11, 2001 and February 26, 1993. Its design conveys a spirit of hope and renewal, and creates a contemplative space. More than 400 trees surround two enormous reflecting pools, which are set within the footprints of the original twin towers. The names of each victim are inscribed in bronze, ringing both of the pools.
