Neil Oliver and the team travel from Holyhead to Liverpool in the second part of their epic journey around the coast of Britain, finding some fascinating insights into the history and people of the area along the way.

Anthropologist Alice Roberts traces the story of how a young boy washed up on the Anglesey coast in 1745 brought the ancient art of bone setting to Britain for the first time. She talks to Dyfrig Roberts, the great, great, great grandson of the original bone-setters on Anglesey.

"There is a story that Evan Thomas used to dislocate bones in order to reset them, on chickens and farm animals, not people of course," Dyfrig explains. "He had four sons who all had the ability to bone-set. The tradition came down to my mother, she used to be able to set bones."

Also in the programme, Neil Oliver meets retired physics teacher Frank Large to find out about one of the last remaining examples of an optical telegraph in the UK at Point Lynas Lighthouse, 14 miles along the coast from Holyhead. The optical telegraph was the text messaging of its day and messages could be sent within minutes from Holyhead to Liverpool.

A terrible shipwreck led to the development of the weather forecast. On the night of Tuesday, October 25, 1859, the iron clad steam clipper the Royal Charter was caught in one of the worst hurricanes to ever hit the UK coast and was smashed on the rocks off Anglesey with the loss of over 450 passengers and crew. Captain Robert Fitzroy was so appalled by the tragedy that he devised the first weather forecasts to give shipping a chance to avoid storms.

The programme also explores the mysterious cave set on The Great Orme, the massive limestone headland off Llandudno. Ogof Llech or 'the hiding cave', features an extraordinary dressed sandstone interior and strange carvings. Archaeologist and historian Neil Oliver tries to unravel it's secrets.

Marine biologist Miranda Krestovnikoff meets mussel fisherman Kim Mould at Lavan Sands, where the biggest mussel fishery in the UK is based, with over 50 per cent of all mussels collected on UK shores coming from this area. And on Llandudno promenade the programme meets Jacqueline Milliband Codman, the great, great granddaughter of the very first Punch and Judy man in North Wales, Professor Codman, who started there in 1860.
