These are not from Provence, but the Basque country, but I thought id post them anyway.
This is a Basque house (on the left
) and a WW2 German Blockhaus. As you enter the beach you see a sign warning you of it, the base has been eroded and it stays up only with its own weight.
These are rocks found at the very Atlantic end of the Pyrenees, the pressure that forced up the mountains created some interesting rock formations.
And this is a war monument.
