The Memorial: Reflecting Absence To open on September 11, 2009, the Memorial consists of two voids that reside in the original footprints of the Twin Towers surrounded by a forest of oak trees. Each void holds a pool of water filled by waterfalls on all sides. Designed by Michael Arad and Peter Walker, Reflecting Absence, was selected from more than 5000 entrants from 63 nations which itself was a testament to the universality of the loss. The Memorial Museum To view the submissions for the Memorial competition, please visit:
Adjacent to the two voids, the Memorial Museum will retell the events of the day, display powerful artifacts, and celebrate the lives of those who died. Visitors will be able to touch bedrock and see the slurry wall that so vividly conveys the enormity of the buildings and the enormity of the loss.
