As this whistle-stop archaeology series draws to a close, presenters Helen Skelton and Alex Langlands find themselves on the wet and windy Pendle Hill. Helen and Alex are in Lancashire this week to explore the setting for Britain's most infamous witch hunt. The two presenters delve into the history of Pendle Hill as they explore Lancaster Castle and talk to archaeologists who claim to have found the site of the supposed coven's meeting place. Their investigation gets Helen and Alex hands-on with James I's notorious book on the occult and uncovers the shocking truth of a nine-year-old girl's role in the deaths of the accused women. Digging Up Britain's Past - Saturday 8:00pm on Channel 5.
