Going Dark Edition 2025
Abbadia Isola
Monteriggioni SI, Italy
The third Going Dark took place during 2—4 October 2025.
2025 was the year that the weather was perfect. This meant that sky conditions were excellent and alongside our astronomy partners, we were able to see the real difference that sensitive dark sky lighting makes to enable us to see the night sky. Thanks to all our partners and participants for being part of our Living Lab.
Participants’ Feedback
— Kathryn Wright (UK)
— Julieta Cignacco (Denmark)
Do we really need all this light at night?
How can we use the right fixtures to protect the dark sky? What is “rolan,” and why should we consider it?
And many more conversations about the importance of seeing our starry sky again.
Meeting designers from around the world who share the same passion for light was truly special.
We talked, learned, walked a lot, played with light, and ended our days sitting under our magical sky.
It was a heartfelt experience one that reminded me why I love what I do.“
