On September 11, 2001, 3,000 people died at the World Trade Center due to a carried out suicide attacks. The Twin towers were knocked down to the ground by two planes that were flown into the buildings.
This memorial was constructed in remembrance to the people that died as well as the six people who were killed in the World Trade Center bombing in February 1993. The names of every single person who died in 2001 and 1993 are inscribed into the panels.
This was put here by a non-profit corporation that uses the money they get to maintain the memorial and the museum at the world Trade Center. On August 2006, the memorial foundation and the Port Authority of NY and NJ began the construction of the memorial and museum. The design was originally Daniel Libeskind idea, he wanted it to be 30 feet below street level. The memorial can get very emotional as your walking through it, as your walking you already feel the pressure and the sorrows. Many people lost their loved ones and many firefighters risked their lives to help.
