I've not finished yet! I'll be visiting that area in the morning. I spotted some enigmatic 'Stones' legends on the MAGIC map which I can't let go. Never spent any time on Primrose Hill before, other than a brief crowded spell during the eclipse...

I'll also hopefully be able to check the book I referenced earlier sometime in the week. And I'm currently working through 'Prehistoric London, its mounds and circles' which concentrates on the Stukeley Druidic school of thought with reference to the London area - Primrose Hill figures in this landscape of course so may well be mentioned. Leave it with me and I'll do what I can.
