Marked on my ign map near to the village of Ymeray is the Dolmen de Chantecoq. I had a good look around, but could find no obvious signs to a dolmen of any kind, but there was a trackway called "Sentier des Roches" which I found near to the railway bridge, so I went for a walk up there.
After several hundred metres was a little area being turned into a little public parkland, with picnic tables etc. Here there is a big natural outcropping of rocks, which may have been used for dolmen making. There is lots of it, and it makes very good slabs, and in many ways reminds me of the rock outcrops / quarries at Tinkinswood.
A bit further up the track, in a private orchard, is what I assume is a menhir, at least there is a 2.5 metre tall slab of rock standing upright. But without any more information, it was difficult to know exactly what there is here.
Something is not right. This message is just to keep things from messing up down the road
