The New York Times headline on Sept. 12, 2001 read: "U.S. Attacked. Hijacked Jets Destroy Twin Towers and Hit Pentagon in Day of Terror." New York Times 9/11 Headline

The attacks killed nearly 3,000 people from 93 nations. 2,753 people were killed in New York, 184 people were killed at the Pentagon and 40 people were killed on Flight 93.

The 9/11 Memorial Museum opened on May 21, 2014. It is located beneath the Memorial plaza. Visitors enter the Museum through a pavilion where two steel “tridents” — remnants of the North Tower’s façade — stand in the building’s atrium. The main exhibition space is located seven stories below the 9/11 Memorial at the bedrock foundations of the World Trade Center.

The Museum offers displays of artifacts from the WTC and 9/11 attacks, interactive exhibitions, contemplative areas and programs that convey individual and collective stories relating the experiences of survivors, responders, area residents and eyewitnesses. A memorial exhibition honors the individual victims of the attacks.
