Earth Hour 2025: landmarks go dark to combat climate change

Famous landmarks and city skylines worldwide temporarily turned off their lights last month as millions participated in Earth Hour.

This yearly global campaign is organised by the environmental group WWF. It urges immediate action to combat climate change.

The rolling blackout began in New Zealand. Auckland’s Sky Tower, Harbour Bridge, and Wellington’s parliament buildings were plunged into darkness.

As Earth Hour moved west, other landmarks followed. The Sydney Opera House, Singapore’s Gardens by the Bay, and Bangkok’s Wat Arun temple went dark. So did Berlin’s Brandenburg Gate, Rome’s Colosseum and the London Eye.

The campaign began in Australia in 2007 and has since grown into a global movement.
