The image depicts a night scene inside a canal lock

The image depicts a night scene inside a canal lock. Two large, damp, concrete walls extend into the distance, forming a channel. The walls are illuminated by overhead lights on poles, one of which is labeled with the number "5". The floor of the lock is a wet, concrete surface with several circular manhole covers. In the foreground, a white railing runs along the edge of what appears to be the deck of a vessel. In the distance, at the far end of the lock, buildings and more lights are visible. The overall impression is of an industrial or maritime setting at night. The location is identified as Markovo, Russia. There are no people visible in the image.
