About This Program ✦
In the Shadow of the Tor is a British television episode presented as a programme. Classified within the episode genre, it concentrates on a single subject rather than extending across a full series. The format centres on one presenter who guides the audience through a focused investigative journey throughout the episode. The presenter sets off on a journey that sweeps across the length of Britain, aiming to untangle the mystery surrounding the Holy Grail legends. By travelling from site to site, and examining each location closely, they try to separate fact from fiction and uncover what, if any, historical truth lies behind the enduring stories of the Grail. Throughout the trek, the investigation ties together three major strands: the legendary Arthurian tales, a range of sacred relics said to be linked to the Grail, and the historical presence of the Knights Templar. Each element is examined in relation to the others, showing how they have been woven into a single narrative over the centuries, and how each appears in the historical record. In the end, the presenter aims to piece together these overlapping traditions, offering a clearer picture of how the Grail myth has been shaped by knights, relics and royal legend. The episode leaves viewers with a concise account of this complex heritage, giving them a straightforward summary to take away.
