The story of Wicca, from Dorset nudist colonies to witches casting spells to ward off Hitler, tabloid hysteria and appearances on Panorama The extraordinary story of Britain's fastest-growing religious group - the modern pagan witchcraft of Wicca - and of its creator, an eccentric Englishman called Gerald Gardner. Historian and leading expert in Pagan studies Professor Ronald Hutton explores Gardner's story and experiences first-hand Wicca's growing influence throughout Britain today. Born of a nudist colony in 1930s Dorset, Wicca rapidly grew from a small New Forest coven to a worldwide religion in the space of just 70 years. It's a journey that takes in tales of naked witches casting spells to ward off Hitler, tabloid hysteria about human sacrifices and Gerald Gardner himself appearing on Panorama.
