Buckingham Palace, Clarence House and Windsor Castle went dark to mark Earth Hour on Saturday, March 22.
The royal family shared the pictures of the historic buildings on its official Instagram page, announcing: "At 8.30pm tonight the lights at Buckingham Palace, Clarence House and Windsor Castle will be switched off in support of @wwf_uk's #EarthHour an initiative to raise awareness of environmental issues."
"Join us for 60 minutes and give an hour for Earth."
Several other renowned landmarks, including the London Eye and the four Tate Museums in London, Liverpool and Cornwall will also support Earth Hour by going dark and switching off lights.
Individuals, communities, and businesses are encouraged to turn off non-essential lights and electrical appliances for one hour, as a symbol of commitment to the planet. Earth Hour, an annual initiative orchestrated by the World Wide Fund for Nature (WWF), is scheduled for March 22 this year, spanning from 8:30 PM to 9:30 PM.
WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
