Editor's Notes
A tiny fishing cove near Gwennap Head at Cornwall's far south-western tip, Porthgwarra is reached down a lane past a huddle of cottages, with a slipway and a tunnel cut through the rock for fishermen's carts. Its granite-framed water made it a memorable filming location for the Poldark television series.
