The National September 11 Memorial commemorates the victims of the terrorist attacks on the World Trade Center. The memorial opened on the 10th anniversary of the attacks at the site of the former twin towers of the WTC.
Design Competition
Soon after the attacks on the World Trade Center plans were made to create a memorial to commemorate the victims of the tragedy. As early as in April 2003, a competition was launched by the Lower Manhattan Development Corporation for the design of a World Trade Center memorial. In total 5,201 submissions were made from 63 different countries.
On January 6, 2004, a 13 member jury selected a design by architect Michael Arad and Peter Walker. The jury lauded the openness of the design, which was dubbed 'Reflecting Absence'.
