Thanks for the info chaps, doesn't seem like ideal bat habitat with no levels. Also looking at Wheals photos it used to be in open country. Now surrounded by crap modern housing!.
Stuey I think our company put some laddered rings in to the top of the laddered shaft you mention. I take it it's related to Crofty?
Are the fenced areas in the recreation field near the boilerworks shaft related too?
