Far below the earth where the twin towers once stood, a cavernous museum on hallowed ground is finally nearing completion.
Amid the construction machinery and the dust, powerful artifacts of death and destruction have assumed their final resting places inside the National September 11 Memorial & Museum.
A vast space that travels down to the bedrock upon which the towers were built, the museum winds its way deeper and deeper underground, taking visitors on a journey to the very bottom.
Already on display are several pieces of mangled steel and metal recovered from the World Trade Center towers, each one telling a different story of the terror attacks that killed nearly 3,000 people.
The first relics that visitors will see are two massive pieces of structural steel that rose from the base of the North Tower. Now the rusty red columns soar above ground into the sunlit glass atrium that encloses the entrance to the museum.
