Dolmen des Rossignols
'It's a suburban dolmen!'
At last something unique and interesting. The dolmen sits below ground level in a large crater in an empty plot amongst an estate of bungalows. I t would seem likely that the dolmen was discovered whilst the foundations for another such bungalow were being dug. If this were true it would explain the row of holes connected by a crack along the top of the capstone. It would appear that an attempt was made to split the capstone before (hopefully before) its significance was realized.
And what a capstone! A good 3m by 4m and about 70cm thick at the edges this is a monster and the only capstone surviving, is ever there were more. It is actually difficult to ascertain where the original entrance was as it was either blocked off in prehistory or some of the uprights were placed wrongly during restoration. Nonetheless this is a very important and impressive dolmen.
The chamber inside is now very low but this could be due to the infill of sandy soil more than anything else, and the capstone appears to be supported by a combination of corbelling and orthostats.
Also, whilst here, I finally managed a break a rule by eating my lunch while blissfully unaware of the 'no picnics' sign, hurray!
The rocks appear to be a mixture of schist and granite and one wonders how far they were dragged to this sandy spot…
