Charles Pétillon’s Superpositions explores the layers of time, memory, and transformation embedded in architecture. Here, a cluster of white balloons spills out from the opening of an abandoned bunker, a relic of wartime history now marked by graffiti and reclaimed by sand. This juxtaposition of the soft, ephemeral forms against the rigid, weathered concrete highlights the contrast between past and present, permanence and impermanence. The balloons seem to push outward, like a breath of air escaping from history itself, questioning how spaces evolve, accumulate meanings, and shift in collective memory.
