The museum spans seven stories, mostly underground, and contains artifacts from the attack on the World Trade Center Towers on September 11, 2001 that include the 80-foot high tridents, the so-called "Ground Zero Cross," the destroyed remains of Company 21's New York Fire Department Engine as well as smaller items such as letter that fell from a hijacked plane and posters of missing loved ones projected onto the wall of the museum. The museum will open to the public on May 21.
