As a monument to human dignity, courage, and sacrifice, the 9/11 Memorial & Museum honors the nearly 3,000 people killed in the terrorist attacks of September 11, 2001 and February 26, 1993, recognizes the courage of those who survived, and salutes those who risked their lives to help others. The exhibits include pieces of concrete from the twin towers and even a fire engine that was used for rescue and care for victims. In addition, there is a collection of personal objects, videos and other materials. In several galleries, the museum shows what the world was like before and after the attacks.
