Interactive Timelines

Dozens of people approach after walking across the Brooklyn Bridge on September Eleventh. They have dust and soot from the World Trade Center in their hair. Behind them, hundreds more people cross the bridge. In the distance is the skyline of lower Manhattan, with a cloud of smoke hovering over downtown.

Interactive timelines chronicle the events of September 11, 2001, the nine-month recovery effort at Ground Zero, and the 1993 World Trade Center bombing. The timelines use images, audio, and video, as well as first-person accounts from the 9/11 Memorial Museum’s permanent collection.

Please note: The timelines contain some graphic images and sensitive content due to the explicit nature of events surrounding the 1993 bombing and the 9/11 attacks.

The 9/11 Memorial Museum’s oral history collection tells the story of 9/11 through recorded interviews conducted from different perspectives, most of which cannot be fully captured through written sources.
