To mark the bicentenary of Val Saint Lambert, Luc Petit’s immersive performance Lumina Crystallis will run from 3 to 27 September 2026. The production combines performing arts and visual arts in a fully immersive experience. Dancers, actors and acrobats cut through space like flashes of light. Their movements are evocative of the glassmakers’ traditional techniques: controlled breath, precise wrist movements and contained strength required to tame the molten material. They appear and disappear in the brightness of the monumental projections, as if shaped by fire themselves. The story draws from the three elements that form crystal: sand, fire and human breath. The heat colours the images, the light sculpts the volumes of the dormitory and the material seems to be transformed before our eyes. In this visual and choreographic ballet, the artists recreate the fragile alchemy which, for the last two centuries, has given rise to crystal at Val Saint Lambert.
