A proud 2.40-meter menhir, which seems to watch over the beach and bathers

Really charmed by this small salt-worker village. On the other hand, it was difficult to take beautiful photos because there were so many cars parked everywhere. Perhaps a victim of its own success?

Picturesque fortified town centre, perfectly maintained and decorated. A small regret: I didn't see any place to attach my bike (apart from the market grate), but my eyesight is failing...
