This day in history, September 12, 2011, the 9/11 Memorial Museum in NYC opened to the public.
The National September 11 Memorial & Museum (also known as the 9/11 Memorial and 9/11 Memorial Museum) is the principal memorial and museum commemorating the September 11 attacks of 2001, which killed 2,977 people, and the World Trade Center bombing of 1993, which killed six.
The memorial was planned right after the attack occurred.
The memorial is located at the World Trade Center site, on the former location of the Twin Towers, which were destroyed during the attacks. The World Trade Center Memorial Foundation was renamed the National September 11 Memorial & Museum at the World Trade Center in 2007.
The winner of the World Trade Center Site Memorial Competition was Israeli architect Michael Arad of Handel Architects, a New York- and San Francisco-based firm. Arad worked with landscape architecture firm Peter Walker and Partners on the design which calls for a forest of trees with two square pools in the center, where the Twin Towers once stood.
On September 11, 2011, a dedication ceremony commemorating the tenth anniversary of the attacks was held at the memorial. The very next day, the memorial opened to the public.
