The Tribute in Light is an art installation created in remembrance of the September 11 attacks.[1] It consists of 88 vertical searchlights arranged in two columns of light to represent the Twin Towers. It stands six blocks south of the World Trade Center on top of the Battery Parking Garage[2] in New York City. Tribute in Light began as a temporary commemoration of the attacks in early 2002, but it became an annual event, currently produced on September 11 by the Municipal Art Society of New York.[3][4][5] The Tribute in Light was conceived by artists John Bennett, Gustavo Bonevardi, Richard Nash Gould, Julian LaVerdiere, and Paul Myoda, and lighting consultant Paul Marantz.[6]
The 88 xenon spotlights (44 for each tower) each consume 7,000 watts.[8] As of 2011[update], the annual cost for the entire project was about $500,000.[9]
Tribute in Light began construction on March 11, 2002, and initially ran as a temporary installation from March 11 to April 14, 2002, and it ran again on September 11, 2003, to mark the second anniversary of the attack.[4] Since then, it has been repeated every year on September 11. It was announced that 2008 would be its final year,[1] but the tribute was continued in 2009.[12]
On December 17, 2009, it was confirmed that the tribute would continue through the tenth anniversary of the attacks in 2011.[13] In 2012, plans were underway for the National September 11 Memorial & Museum to assume the lease for the MTA property used during this tribute, and to begin transitioning operation of the tribute from the Municipal Art Society to the memorial foundation.[14]
The lights are produced by an Italian company named Space Cannon,[15] which sends a team every year to help with the installation.[9] A Las Vegas-based company, Light America, was also part of the team who implemented the project.[16]
Each year, about 30 technicians, electricians, and stagehands work for about ten days to install the lights. During a testing phase of several days, observers in Brooklyn, Staten Island, New Jersey, and uptown Manhattan help make sure that the beams are adjusted accurately.[9]
The project was originally going to be named Towers of Light, but the victims' families felt that the name emphasized the buildings destroyed instead of the people killed.[17]
A permanent fixture of the Tribute in Light was at one point intended to be installed on the roof of One World Trade Center,[18][19] but it was not included in the finished design.[20]
Since 2008, the generators that power Tribute in Light have been fueled with biodiesel made from used cooking oil collected from local restaurants.[21]
Effects on birds
The light pollution from Tribute in Light has caused confusion for over a million migrating birds, trapping them in the beams.[22] Even at an altitude of several miles, birds can be affected by the lights.[7] As a result of this effect, the beams are switched off for 20-minute periods to allow the birds to escape.[23] To ensure the lights do not affect migrating birds, the Municipal Art Society works with the NYC Bird Alliance on the illumination.[24] A 2017 study found that the installation "dramatically altered multiple behaviors of nocturnally migrating birds—but these effects disappeared when lights were extinguished".[22][25]
In popular culture
Tribute in Light was featured in Boyz II Men's music video for "Color of Love". It made a notable appearance during the opening credits of Spike Lee's 2002 film 25th Hour. The tribute was also shown and referenced in the CBS series Blue Bloods. These lights were featured in the music video of U2's "You're the Best Thing About Me".
