Earth Hour: World Landmarks Switch Off Lights

Posted By on March 24, 2013

Buckingham Palace, the Empire State Building, the Eiffel Tower and the Kremlin – along with a slew of other landmarks around the world – went dark to draw attention to climate change.

More than 150 countries took part in Earth Hour, organised by the World Wildlife Fund. People across all continents switched off their lights for 60 minutes at 8.30pm local time on Saturday.

In the UK, the palace was joined by Elizabeth Tower, which houses Big Ben in the Palace of Westminster and the Southbank Centre on the banks of the River Thames. [full screen]
