The image shows an empty underground tunnel with arches and a large circular window at the top. The tunnel appears to be made of stone and has a dark and gloomy atmosphere. The floor is made of concrete and the walls are made of brick. The arches are arched and the light from the window casts a warm glow on the walls and ceiling. In the center of the tunnel, there is a small altar with a green cloth draped over it. The overall mood of the image is eerie and mysterious.
