虚無の塔：鉄筋コンクリートの垂直な亀裂

Design a memorial void in the manner of Daniel Libeskind as a tall unheated triangular shaft of bare concrete, entirely empty, lit only by one narrow slit high on a wall that admits a sliver of daylight and outside sound. Compose rough board-marked concrete walls converging as they rise, a plain concrete floor with nothing on it, a single steel ladder fixed out of reach, no artificial light, near-darkness with one bright angled shaft, low view straight up the shaft, 24mm lens, interior photography, ultra photorealistic, 8K
