クレーターに埋め込まれた美術館：円錐形のヴォリュームと黒い石

Design a volcano museum in the manner of Hans Hollein's Vulcania — most of it buried in the volcanic plateau, announced above ground only by a truncated cone clad in black lava stone and lined with gold, and a long cleft cut into the earth that visitors descend. Compose a squat inverted cone of dark basalt with a gilded inner face catching the sky, a deep linear crack in the grass plateau leading down to the entrance, the extinct volcanic range of Auvergne behind, no other structure visible, cold overcast light, elevated three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
