Jerome,
Certainly the picture is captivating and impossible to go by without thinking of safety. Maggie and Tom have already reflected in their comments the aura of drama and fear that might be associated with what went on there. At first I thought of a prison camp, of course!
Now with the drama having being duly noted, I'm interested in the tall narrow building behind the immediate structure we see before us. I think of a church or school tower.
This could, of course be an old industrial site, some place where furniture, screw drivers or springs were made. The tower can't be so easily explained. For a prison, one generally needs more than one, at least here in the USA. The tall building could house some process that requires that height, but then usually one would expect that to be in naked steel with pipes open to the exterior.
So all we can be is fascinated. Thank goodness we do not have the entire story told every time as this allows us to exercise our imagination.
Thanks for sharing!
Asher
