British Prime Minister David Cameron and his wife Samantha visited New York's World Trade Center site on Thursday.
The couple viewed the construction project from the 21st floor of the new One World Trade Center and looked at renderings of what the skyscraper will look like upon its completion.
New York City Mayor Michael Bloomberg later greeted the couple at the 9/11 Memorial and pointed out the waterfalls that outline the footprints of the former Twin Towers.
Samantha Cameron placed a bouquet of flowers on the memorial which contains the engraved names of every person who died in the World Trade Center on September 11, 2001.
The visit to World Trade Center was just one stop on the Cameron's three-day official visit to the United States.
