The image shows an underground tunnel with a metal railing on the top. The tunnel appears to be made of brick and has a concrete floor. The walls of the tunnel are covered in ivy and there is a sign on the right side of the image that reads "Schloss Schloss" which translates to "The underground tunnel" in English. Below the sign, there is an image of a train track that runs through the tunnel. The track is empty and there are no people visible in the image. The image appears to have been taken from a high vantage point, looking down on the tunnel and the train track.
