Cairn oleronnais Pile of stones

Mireille, I would like to add my grain of salt . I know especially the cairns mountain which are used to mark the trails ; they are therefore very useful. At the edge of the sea, I think that those that ride in them are trying to defy the laws of balance.

I didn't know the name. I have seen many of them on the island of Oléron and that is impressive, one wonders how they remain in equilibrium with the wind.
