In a secluded valley in Wales, what may be a medieval or even Roman trackway leads down to a natural spring. Right in the middle of it is a megalith, a large standing stone, perhaps 3,000 years older than the track. Nearby, there are the remains of what appears to be a Neolithic tomb, and overlooking it what is reputed locally to be a Norman – or maybe Roman – watchtower. Stones in a ruined building on the site have early Christian symbols inscribed on them, leading to speculation that it may have been an early chapel. And in and around the spring itself the landowner has found hundreds of Roman coins, medieval jewellery, blades, buckles, statuettes and a strange collection of weirdly carved stone heads. Time Team set out to uncover the story behind this strange collection of archaeological features and finds.
