September 11, 2001

On the morning of September 11, 2001, Al-Qaeda terrorists hijacked four airplanes. Two of them — American Airlines Flight 11 and United Airlines Flight 175 — flew into the Twin Towers of the World Trade Center in Lower Manhattan. Within 102 minutes, both towers collapsed. 2,977 people died — the deadliest terrorist attacks in history.

September 11 changed New York and the world forever. The city experienced a collective trauma — and demonstrated a resilience that earned it the nickname "the city that refuses to give up." At the site of the Twin Towers now stand the 9/11 Memorial (the reflective pools), the 9/11 Museum, and the One World Trade Center (Freedom Tower, 541 meters) — as symbols of perseverance.

For visitors from abroad, the Memorial is a place of silence and respect. It is appropriate to remain quiet, refrain from taking selfies, and treat the site for what it is: a burial ground.
