The image shows the interior of a large concrete tunnel with a high ceiling. The walls of the tunnel are covered in cracks and grime, and there are several small lights hanging from the ceiling. In the center of the image, there is a small opening in the tunnel, which appears to be a cave or underground passage. The floor is made of concrete and is empty, with no people or other objects visible. A person wearing a green jacket is standing in the foreground, looking up at the entrance.
