I don't know the specific topography of the area or what archives would show, but I know of a bunch of smokestacks that used to be around, at factories, that aren't there any more. Same with the factories. I don't mean in Europe, I'm just talking generally. Back in the old days there were a lot of factories that burned down and chimneys that eventually had to be demolished since they became a safety hazard. Interesting marble topic/discussion
