Blackpool Tower is among the famous landmarks which are set to be plunged into darkness as millions of people prepare to switch off lights for an hour to raise awareness about climate change.
Buckingham Palace, London’s Tower Bridge, Old Trafford football stadium and the Elizabeth Tower, widely known as Big Ben, are also taking part in the World Wildlife Fund’s Earth Hour today.
The event, which takes place in the UK from 8.30pm, will see more than 700 landmarks around the world switch off their lights, including Christ the Redeemer in Brazil, France’s Eiffel Tower and more than 30 Unesco World Heritage Sites.
Blackpool Tower also joins The Palace of Westminster and Edinburgh Castle among the UK sites taking part.
London’s South Bank will be the “focal point” for the Earth Hour switch off, WWF said, where visitors can experience candlelit dinners in many of its bars and restaurants.
British tennis champion Andy Murray, a WWF global ambassador, has backed the campaign along with Prime Minister David Cameron and Labour leader Ed Miliband, the charity added.
Earth Hour was launched in 2007 in Australia and has since spread around the world. Last year nine million people in the UK took part, WWF said, as part of a record-breaking chain of 162 countries.
