Djerba Heritage Festival in Djerba
The event most likely corresponds to the Journees du patrimoine mondial de Djerba (Djerba World Heritage Days), a young festival launched in September 2024 to mark the island's 2023 UNESCO World Heritage inscription, with a second edition held September 5-7, 2025 featuring workshops, exhibitions, and music tied to Djerba's Amazigh, Jewish, and Ibadi Muslim heritage.
This is a young, real event still establishing its identity, so a long-form narrative is not written to avoid inventing history beyond what is documented.
