In the creeks near Marseille, 37 metres underwater, lies the only submerged cave on the planet that's covered with cave paintings. On its damp walls, people have painted horses, bison, ibex and even penguins – animals that were present in the south of France during the Ice Age. The oldest paintings date back some 27,000 years.
