Stones Reef and Godrevy Lighthouse, St Ives Bay, Cornwall. The reef extends from the headland at top of St Ives Bay so you can imagine what happened to shipping before the lighthouse was built. It's no coincidence there are two beaches nearby called "Deadman's Cove" and one called "Hell's Mouth".
St. Ives harbour and the sea beyond. Lawrence Stern's cottage (writes Rosamunde Pilcher) stood where Thomas Millie Dow's large house had stood, above St. Ives and the bay, and surrounded by a beautiful walled garden.
