I visited this site in May 2012 on the way from Würzburg. The ironworks have gone out of production but they are the only intact example in Western Europe and North America of an integrated ironworks built in the 19th and 20th centuries. The whole visit was quite a short but informative one. I would have never visited this place if it weren't for UNESCO. However, visiting it helped me picture and understand how important such places were in the industrial revolution.
