White flowers at the names of victims on the Memorial

September 11, 2001 Commemoration

Each year on the anniversary of 9/11, the families of victims gather for a ceremony on the 9/11 Memorial plaza to read aloud the names of the 2,983 men, women, and children killed in the September 11, 2001 attacks and February 26, 1993 bombing of the World Trade Center. Six moments of silence mark the times when each of the World Trade Center towers was struck, when each tower fell, and the times corresponding to the attack at the Pentagon, and the crash of United Airlines Flight 93 in Pennsylvania.

Tribute in Light
