"The museum features 60,000 artifacts — a mix of physical evidence, first-person testimonies, and historic records — from the September 11, 2001 and February 28, 1993 terrorist attacks on the World Trade Center. Archaeological remnants are also on display, including the 'Survivors' Stairs' and the 'Last Column.' The memorial outside is free and open to the public, with the names of every person who died in these attacks inscribed on the edge of the two reflecting pools." - Travel + Leisure Editors
