For a decade, Oh les beaux jours ! has painted Marseille in luminous colors each spring, bringing literature into collision with music, drawing, and the stage. The 2026 edition marks its 10th anniversary with 80 encounters and spectacles across the city, from La Criée Theatre to unexpected venues. Expect hybrid forms, international voices, and a festival that treats books as living, unruly things—not museum pieces. This year introduces a choose-your-own-adventure book-game that lets you wander the festival's backrooms, plus a dedicated boutique peddling limited posters, tote bags, and postcards designed by atelier25.
