Commemorating the September 11, 2001 bombing, the national September 11 memorial and Museum is a significant landmark remembering the victims and volunteers of the said tragedy. Located at the World Trade center site, this place occupies 30 feet below the street level. On 2003, the Lower Manhattan Development Corporation launched a worldwide design competition which was participated by individuals and teams. On January 6, 2004, the Reflecting Absence was chosen as the winner from 5,201 entries out of 63 participating countries designed by Peter Walker and Michael Arad.
The overall design of the construction is one of the reasons why this place is so famous. The callery pear tree survived the attacks of the 9/11 tragedy. This has been a pre-eminent attraction in the memorial along with six other trees which were called “survivor Tress”. On May 21, 2004, the museum was opened to the public with 2,000 oral histories of the victims, 10,300 artifacts and 23,000 images as well as the steel from the Twin Tower. This place overall encloses 110,000 square feet of space which is accessible for the public.
The September 11 attack at the World Trade center has sacrificed many innocent lives. Commemorating the lives that were lost and the heroism of volunteers are great efforts to make worthy their sacrifices.
