Two huge beams of light point skyward not far from where the World Trade Center was in New York.
The installation bears the name of Tribute in Light (in French: "Hommage en lumière") and it shines to honor the memory of the victims of the terrorist attacks of September 11, 2001. This Saturday, New Yorkers and the United States celebrate the 20th anniversary of the World Trade Center attacks.

For almost two decades, the "Tribute in light" has become the symbol that honors the victims killed in the attacks that hit the Twin Towers. The beams of light reach up to 6.5 km into the sky and consist of eighty-eight 7,000 watt xenon bulbs positioned in two 15 m squares, echoing the shape and orientation of the towers binoculars. The facility can also be viewed within a 100 km radius of Lower Manhattan.
