Most of us remember where we were on 9/11. We watched the events in New York, Pennsylvania, and Washington D.C. unfold from our windows, our televisions and on the ground. The artifacts and installations featured in the 9/11 Memorial Museum tell the story of what happened on 9/11, what led up to it and its aftermath. | National September 11 Memorial & Museum
