Collaterals to Stonehenge include this "monument of vertical stones", remains of the old mill, near the (rail) station, in Plouharnel-Carnac.
Or, that's the best I could make of "Menhirs du vieux moulin, pres de la Gare".
Plouharnel and Carnac are communes (do two communes make a region?) in France:https://en.wikipedia.org/wiki/Plouharnel
... Plouharnel is a commune in Francehttps://en.wikipedia.org/wiki/Carnac
... Carnac is a commune in Francehttps://en.wikipedia.org/wiki/Carnac_stones
... is our pile of stones, perhaps, from one of these sites?
Q/ Do you have any postcards of any other Collaterals to Stonehenge?
