You step out on a coastal road where basalt cliffs meet a restless sea and the old ore-loading mouths stare like portholes into history. Salt wind pushes at your jacket; below, the sea dares you from the drop. The guide points to carved tunnels and the mechanical hatches that once fed zinc powder into waiting ships — the stone still smells faintly of metal and old smoke.
