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.
World Trade Center History
The Twin Towers were the centerpieces of the World Trade Center complex. At 110 stories each, 1 WTC (North Tower) and 2 WTC (South Tower) provided nearly 10 million square feet of office space for about 35,000 people and 430 companies.
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.
The registries offer a digital repository of stories and collective memory from the witnesses, survivors, rescue and recovery workers, and commemorators of 9/11 and the February 26, 1993 World Trade Center bombing.
