The first Earth Hour took place in 2007. Since then, it has blossomed into a massive global celebration that sees not only millions of individuals hitting the switch for an hour, but major landmarks as well.
Every year, the Burj Khalifa switches off and this year, for the first time, the Sultan Ahmed Mosque (Blue Mosque) in Istanbul and the Hagia Sophia and Bosphorous Bridge that connects Europe and Asia will be switching of as well.
In Jordan, a candlelit march will take place on one of the city’s oldest streets in Jabal Amman, and the lights of Al Karak Castle will be switched off as well.

Small events will take place in Egypt and Iran and other countries across the Middle East and North Africa – all you have to do is head over to WWF’s Earth Hour site to find out how you can get involved in your own community or country.
And if there isn’t an event, make one! Or have your own private party in the dark.
Whatever you choose to do, remember this. While Earth Hour is a symbolic international gathering designed to celebrate a healthier planet, the idea is to get people thinking about ways that they can reduce their footprint for the long term.
“It’s a brilliant reminder that together we can make change happen, and it gives us a chance to think about the small things we can do everyday to help create a brighter future,” writes WWF.
“So whether you reflect under the stars or celebrate by candlelight, it’s a moment to say you’ll do your bit to protect our planet – not just for one hour, but every day.”
This year’s Earth Hour takes place on March 29, from 8.30-9.30pm (local time.)
