Holywell Bay | Looking for Cornish Mines and Abandoned Military Buildings

I head to the Atlantic Coast of Cornwall, near to Perranporth, to explore the beauty of Holywell Bay, and the dramatic cliffs above it. Along the way, I discover abandoned mine shafts, cold war nuclear bunkers, and much else besides.
