海边的小教堂：一片混凝土折成的壳

Design a tiny chapel in the manner of Paulo Mendes da Rocha's Capela de São Pedro — a single folded concrete plane forming floor, wall and roof in one continuous gesture, open at both ends so the sea breeze passes straight through and the altar is silhouetted against the landscape. Compose one raw concrete surface bending from ground to roof, completely open at each end with no door or window, a plain concrete altar and a few benches, coastal grass and rock around, hard bright light with the interior in deep shade, eye-level view along the axis, 28mm lens, architectural photography, ultra photorealistic, 8K
