This superb ducumentry follows Tony Robinson on his 4 day walk along St Cuthbert's Way.
He looks into Northumberland and the mysterious heart of the Dark Ages, to a time when the huge Kingdom of Northumbria was being torn apart, by internal strife and wars with rival kingdoms.
In the middle of this turmoil, a small group of radical Irish monks persuaded the largest kingdom of pagans in the country to put down their swords and become Christians. The charismatic figure at the centre of this mission, who later became a saint, wasn't Irish but a Briton named Cuthbert.
Begins at Melrose Abbey and follows St Cuthbert's Way, through the Eildon Hills and along the River Tweed to St Boswells, uncovering the early religious life of St Cuthbert and the Celtic monks who came to this area. It's also possible to take a detour to Bemersyde Hill for a spectacular view over Cuthbert's early stomping ground.
