In the second episode, Ifor explores why water crops up again and again as the essential element in many of our most holy places. Why has a yearning for pure natural water always been bound up with our spiritual beliefs? His journey takes him to our oldest mass baptismal pool which marks the place that Scottish Picts first came into the Christian fold, the site on Loch Ness where Celtic missionaries battling the forces of paganism first encountered the legendary monster, a healing well where a young woman was reputedly brought back to life by having her severed head re-attached to her body, and a 2,000-year-old holy spring that has become a major international brand.
