Don't think it is only industrial - in fact the industrial remains are only noticeable if you hunt for them, though there are several chunks of old masonry. We were taken here because of the typical Tuscan landscape visible from its elevated position - and that was fantastic! However, the star feature for me is the historical evidence of mills which used the thermal spring water to operate all year round. The thermal springs still run and there is warm water flowing in channels across the site.
There are several information boards with English translation, but they are all a bit battered and lack a good diagram of the industrial remains.
