The Tribute in Light is an art installation of 88 searchlights placed six blocks south of the World Trade Centre on top of the Battery Parking Garage in New York City to create two vertical columns of light to represent the Twin Towers in remembrance of the 11 September 2001 attacks. Tribute in Light began initially as a temporary commemoration of the attacks in early 2002 but became an annual commemoration, currently produced on September 11th by the Municipal Art Society of New York.
On clear nights, the lights can be seen from over 60 miles away, visible in all of New York City and most of suburban Northern New Jersey and Long Island. The two beams cost approximately $1,626 per day to run. There are 88 xenon spotlights which each consume 7,000 watts.
