純粋に幾何学的な記念噴水：三角形、円柱、立方体

Design a civic monument in the manner of Aldo Rossi's Segrate fountain — a memorial assembled from nothing but primary solids: a tall cylinder, a triangular pediment slab and a stepped cube, set on a bare paved platform with a shallow channel of water, and no inscription or figurative element at all. Compose a white cylindrical column beside a plain triangular gable standing free, a cubic block with a square opening, a shallow rectangular water basin, an empty concrete plaza with no planting, hard midday sun with strong geometric shadows, low frontal view, 28mm lens, architectural photography, ultra photorealistic, 8K
