The image shows a tunnel lined with logs stacked from floor to ceiling. The logs are mostly brown and some have a white or gray patina. The logs are stacked in a staggered pattern and the ends of the logs can be seen in the image. The tunnel appears to be dimly lit, with light coming from the end of the tunnel. At the end of the tunnel is a wooden walkway with a metal railing. The wall behind the walkway appears to be made of stone. The tunnel may be an old mine shaft or a timber-framed structure. The logs are arranged in a way that gives the impression of an open-air tunnel. The logs are old and worn, adding to the feel of the tunnel.
