Ahead of World Environment Day on 5 June, some of the most famous buildings in Luxembourg will be lit up in green and blue this weekend.
The Philharmonie, Fonds Belval, Chateau d'eau and Stade de Luxembourg, as well as Spuerkees bank and the Cloche d'Or shopping centre will all participate in the initiative at different times between 3-5 June.
The event will be held in support of Save Soil, a global environmental organisation campaigning to stop soil degradation. Its founder, Sadhguru, is currently undertaking a 100-day, 30,000-kilometre motorcycle journey from London to southern India to raise awareness.
Other participating monuments worldwide include Niagara Falls and Montreal's Olympic Stadium.
