Paris will be completely plunged into darkness in March!

Here’s a tradition that Paris wouldn’t miss for anything in the world: Earth Hour. What is it all about? It’s a global movement initiated by WWF, where we turn off the lights of the most famous monuments around the globe. This 2026 edition, happening on Saturday, March 28, will have a special flavor as it celebrates 20 years of the event!

An international movement for the environment

A seemingly simple action that carries a very special symbolic weight. Once a year, 185 countries celebrate Earth Hour and thereby demonstrate their ecological commitment. New York, London, Sydney, Singapore, as well as Paris, Lille, Rouen, Lyon, Marseille, and La Rochelle join forces and are plunged into darkness for one hour. 

What’s the goal of such an initiative? To collectively raise awareness about our hyper-connected lifestyles and consumption habits and the dangers our planet faces. More concretely, this blackout, though it lasts only an hour, allows us to save several thousand tons of CO2.

About twenty Parisian monuments turned off

In Paris, this means that the most iconic monuments and places in the capital, usually lit up continuously, will be turned off. This includes the Eiffel Tower, the Arc de Triomphe, the Louvre Museum, Notre-Dame de Paris, the Sacré-Cœur, the Champs-Élysées, the Vendôme Column and Square, the Column of the Throne, the City Hall, the Panthéon, the Hôtel des Invalides, the Petit Palais, the Place de la Concorde, the Bir-Hakeim Bridge, the Pont-Neuf, the Climate Academy, the Saint-Sulpice Church, as well as the town halls of the 5th, 9th, 14th, and 18th arrondissements. On this occasion, some establishments in the capital are also joining in the fun: this includes the Grand Café Fauchon which will offer.a candlelit dinner. Three menus crafted by Chef Baptiste Limouzin will be available that evening.
