Earth hour at our museums and galleries

To get involved all you have to do is switch off your lights for one hour! More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011.
The lights at the following landmarks were also switched off in 2011: Eiffel Tower, Sydney Opera House, The Forbidden City, Buckingham Palace, Golden Gate Bridge and Christ the Redeemer statue.
It is hoped that this event sends a powerful message for action on climate change and shows how great things can be achieved when people come together for a common cause.
