This is the so called ‘crocodile’ in the ‘LaPaDu’ (Landschaftspark Duisburg) in Germany. The LaPaDu formerly was a coal and steel production plant.
After its closing it has been changed to a freely visitable park that exhibits its industry culture. Light installations at night make the LaPaDu an eldorado for photographers.

This must have been a very interesting spot to visit.
This looks very unnatural

I see. I consider PLAYraw as DEVELOPraw, because I’d like to learn how to use the software a bit better.
