Penlee Point, on the Rame Peninsular in Cornwall, just the other side of Plymouth, is full of history, both natural and man-made. Heading down to the rocky coastline we walked over a camomile lawn, relishing its fragrance, and passed bee orchids, purple vetch, speedwell and foxgloves. At Penlee Point itself we found Queen Adelaide's Grotto, an eighteenth century lookout point, and there are apparently various Victorian and Edwardian defences in the area. As we swam from an idyllic sandy cove round through channels to sheltered rocky pools, we were passed by a procession of naval destroyers and frigates going back and forth from Plymouth Sound. There was masses of marine life to see including anenomes, sea squirts and some amazing seaweed called thongweed which looked just like a mermaid's hair.
