When night falls on Friday, September 26, the Great Revelin in Korčula will turn into a canvas upon which the sea and its hidden guardian – the Posidonia oceanica – will speak.
Come to the light show of Sunce
After a successful premiere on Hvar, the same story arrives in Korčula. From 8:00 PM to 11:00 PM, visitors will be able to enjoy a unique light show that unites art, science, and emotion. The projection presents a conversation between a sailor and Posidonia – a seagrass that, though invisible to the eye, plays a crucial role in preserving the Adriatic.


– We gave Posidonia a voice and a face to help people understand its importance. It produces oxygen, stores CO₂, stabilizes the seabed, and provides shelter for numerous marine species. For thousands of years, it has shaped our sea, nurtured it, and protected it. To preserve Posidonia means to preserve the sea and the way of life along the coast, – say representatives from Sunce, the main organizer of the event.
And where do you anchor?
Often unseen and underestimated, Posidonia takes center stage in the projection – her voice reaching out to people, especially sailors, inviting them to pause and rethink their ways. For anchoring in her meadows is one of the main reasons they are vanishing.
– Posidonia grows very slowly, from 0.4 to 6 cm per year, and once the meadows are destroyed, their recovery takes a very long time. Because of its ecological importance and sensitivity, it is protected by law in Croatia, something many people are unaware of. We hope this event will inspire sailors and all sea lovers to truly ask themselves next time: ‘And where do I anchor?‘ – emphasize the team from Sunce.

The projection’s author, Tomislav Brđanović, noted that the entire creative process was a challenge, as this is the first AI-generated film of its kind in Croatia. Through months of experimentation and development, the project ultimately opened up entirely new possibilities for promoting marine conservation.
Take a photo and win prizes!
In addition to the visual experience, visitors will be able to explore Sunce’s booths, learn about the organization’s work, and find out how they can contribute to marine protection – through volunteering, membership, or donations.
For an extra touch of fun and inspiration, there will also be a Posidonia-themed photo corner. Those who take a photo, post it as a story, and tag Sunce will have a chance to win symbolic, sea-inspired prizes.
This event is part of the Interreg BIOPRESSADRIA project, through which Sunce and its partners from Croatia and Italy are developing strategies to reduce the negative impact of tourism on coastal and marine biodiversity.
