About this programme

2/16. An invitation to excavate the remains of what is thought to be one of Scotland's earliest chapels on the Isle of Mull provides Tony Robinson and the team with one of their biggest, most rewarding, challenges. In a forest outside the town of Tobermory, they believe they have discovered a settlement established by St Columba, who brought Christianity to northern Britain - but the remoteness of the location and the discovery of human remains threaten what could be a once-in-a-lifetime find.
