La nuit est belle! returns on the weekend of April 11, 2025 for a 5ᵉ edition dedicated to the culture of the night. The gamble has paid off: habits are evolving, and switching off public lighting in the dead of night is now widely accepted. Today, thanks to advances in lighting technology, the challenge is no longer simply to switch off, but to light intelligently, guaranteeing safety and efficiency. This is the role of public lighting. In Greater Geneva, more than two-thirds of municipalities have adopted daily night-time extinction. On the French Genevan side, over 90% of communes and their residents have opted for partial or total night-time extinction. For this 5ᵉ edition, La nuit est belle! will honor these communities committed to an approach that respects the environment and nocturnal heritage. The 2025 event will also reinforce its call to reduce excessive artificial lighting, encouraging shopkeepers, residents and businesses to get involved in this transition. Convinced that culture is a powerful lever for raising awareness and bringing about change, the founding and organizing partners – Greater Geneva, the Natural History Museum, the Geneva Astronomical Society and the Maison du Salève – are placing this year’s event under the banner of “Culture… at night”.
