Water Features used to create a unique memorial at the site of Ground Zero, New York

Over 5,200 proposals were submitted and Michael Arad's design chosen to remember nearly 3,000 people who lost their lives in the 9/11 attacks which took place in New York ten years ago to the day.

There are two water features, one on each site to represent World Trade Centre plaza are over an acre in size each and water glides down each side 30 feet making this the largest manmade fountain in America. 660,000 gallons of water re-circulate 24 hours a day, seven days a week.

The two fountains opened to the families of people who lost their lives on 9/11, it opens to members of the public on the 12th September 2011.

The names of those lost are etched in bronze panels around the edge of the water feature, a powerful reminder of the largest loss of life resulting from a foreign attack on American soil. At night the feature is lit.
