Here, in the Hallstatt salt mine, modern visitors descend in wooden lifts, past walls streaked with grey and white veins, into a labyrinth carved by human hands so long ago that the Bronze Age was still a distant future.

The same sound, one imagines, that greeted the first miners who ever broke through this mountain’s skin.
