Underground Arrival Hall Interior: Pyramid Light Well and Axis

Design a museum arrival hall inspired by the Louvre Pyramid. Organize a spacious underground lobby illuminated through a central glass pyramid light well, connecting multiple museum wings with intuitive circulation. Use limestone, polished stone, stainless steel, ultra-clear glazing, and restrained detailing to create an atmosphere of timeless elegance and geometric clarity. A wide beige stone concourse with a glass pyramid overhead casting a diamond grid of shadow across the floor, a spiral stair and open cylindrical lift descending at the centre, three tunnel entrances aligned exactly with the axes, visitors dispersing in all directions, bright daylight from above, wide upward view, 24mm lens, interior photography, ultra photorealistic, 8K
