A rather long but excellent essay about Castlerigg and axes - I think the approach is to do with 'phenemenology' of the place, and nothing to do with burials or the sanctuary, though I did like Pryor likening Castlerigg/langdale axes with Stonehenge/Preseli.... Why sanctuary though? must be victorian
“Strangely, there is a link between the two places: they are both high and remote, with spectacular views; but more than that, the rock itself is sharp, angular, strangely columnar and almost artificial in appearance. It would not take an overactive imagination to see these rocky outcrops as something removed from this world, perhaps assembled or created by a race of altogether more powerful beings than us.” (Pryor, 2004, p.151)
