September 11 attacks
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks.
9/11 Living Memorial Plaza
The folded part of the flag is reminiscent of the collapse of the towers in a cloud of dust. The flag morphs into a six-meter high memorial flame representative of a torch. It is the first and only monument outside of the United States which lists the names of the nearly 3,000 victims of the 9/11 attacks.
