Thirty thousand years in the making, this story begins with the drama of the earliest-known human burial in western Europe. Huw delves into the biggest prehistoric copper mine in the world, and visits the mesmerising site of an Iron Age hillfort. He reveals the true scale of the Roman occupation, and shows how Welsh saints carried the light of the gospel to the rest of the Celtic world, and left a mark on their homeland that we can all still read today.
