There are over 300 shipwrecks in Lyme Bay alone, from old galleons to submarines. Dan dives to discover the story behind some of the more unusual vessels, a number of top secret WWII tanks that sank in a D-Day landings rehearsal known as Exercise Smash.

Beyond the importance of the stone, the programme follows families of peregrines and little owls that live in these rock faces. How have they fared in this scorching summer?
