Around the globe Saturday, lights went out for Earth Hour. The annual event, which is meant to raise awareness for climate change, asks participants to power down for just one hour. This year, Earth Hour occurred Saturday from 8:30-9:30 p.m. local time around the world.

The non-profit behind Earth Hour is based in Singapore and works in partnership with the World Wildlife Fund and other volunteer organizations. The hope, organizers say, is that this one hour will make people more aware of how much energy they consume every day and change consumption habits. Earth Hour began in 2007 in Sydney, Australia. Here’s a look at darkened cities from across the globe, from just some of the 162 countries organizers say are taking part in Earth Hour 2015.

Seen here, national monuments and famous skylines from cities far and wide plunge into darkness.
