Stadium in a Quarry: Turning Rock Faces into Grandstands

Design a stadium in the manner of Eduardo Souto de Moura carved into a disused granite quarry, where two ends stay completely open to the rock face and the landscape instead of being enclosed by seating. Compose two facing concrete stands with a cable-suspended roof spanning between them, the quarry's raw grey rock wall filling one open end and the valley the other, exposed board-marked concrete, green turf, cool overcast northern light, wide view from the pitch level, 24mm lens, architectural photography, ultra photorealistic, 8K
