An indoor underground space with green tiled walls and floor, illuminated by artificial lights. Two large square columns are positioned in the center foreground, each topped with a white rectangular light box. The columns are grey and feature rows of rivets along their vertical edges. The walls are covered in small green square tiles, and the floor is also tiled with larger green square tiles. The ceiling is dark green and appears to be concrete. Linear fluorescent lights are mounted along the top of the walls, near the ceiling. Stairs with a black metal railing are visible on the left side of the image, descending into a lower area.
