World Trade Center Site Memorial Competition

The competition began April 28, 2003 and the winner—Michael Arad and Peter Walker's Reflecting Absence—was revealed January 14, 2004, in a press conference at Federal Hall National Memorial.

On March 5, 2002, Governor George Pataki, Mayor Michael Bloomberg, and the Lower Manhattan Development Corporation (LMDC) jointly announced plans for an interim memorial to the victims of the September 11 attacks in 2001 and the 1993 World Trade Center bombing that happened on February 26 that year.

On January 2, 2003, LMDC and Port Authority announced that a series of public meetings would take place to discuss a future World Trade Center Site Memorial.

On April 8, the LMDC announced the creation of an Advisory Committee to ensure that the Competition Guidelines are incorporated into the final design, which had undergone revision since January 14.

On April 13, the LMDC announced that associate architect Davis Brody Bond would assist Arad and Walker with their final design.
