Abandoned 'ramparts'

These 'raddlepits' rise like grim, abandoned castle walls out of a ridge near Wootton in the Weaver Hills in east Staffordshire. Up there, I only saw sheep and what appeared to be semi-wild horses, so these ruins are not visited much.

In fact, they are what remains of the lead mines hereabout; I guess that they are giant kilns built into the hillside over deep shafts.

The term raddlepit is used also at a Derbyshire lead-mine, so I thought a raddle-pit might actually be a denotation for a lead mine, but I haven't yet found any evidence of that.
