The Colosseum shone as brightly as ever until 8:30 p.m. local time on March 28, 2009, when Rome turned off the monument's lights for Earth Hour 2009.
The voluntary, annual global blackout, which aims to ease global warming, began in Sydney in 2007 with the nonprofit WWF. In 2009, 2,712 cities, towns, and municipalities in 83 countries signed up to participate in Earth Hour. The movement is a symbolic gesture in support of action against global warming.

Times Square glows slightly dimmer during Earth Hour on March 28, 2009.
It's not clear how much energy was saved by Earth Hour this year. Unlike in previous years, event organizer WWF is not releasing energy-savings estimates.
"We think the value of Earth Hour is the lights going off," said WWF spokesperson Leslie Aun, "not the energy savings."March 30, 2009
