I visited Volklingen Ironworks in May 2010 and spent at least 2 hours wandering and climbing over the entire works. It was an amazing experience. I had spent 8 years of my younger like working as a welder in the Bethlehem Steel Sparrows Point shipyard, immediately adjacent to the huge Beth Steel furnaces and mills, across a small inlet from the (odoriferous) coke ovens (where we'd steal coke for our warming fire pots during the winter). Knowing what it was to work at Sparrows Point, and then visualizing what it would appear as a quiet(!) ghost town sent shivers down my spine. I only wish I knew German to be able to read the workers' graffiti!! (I know what I left as graffiti at Sparrows Point). I will go back again and take even more time to walk and climb it.
