The Camino (S02E03)

For more than a thousand years, Christian pilgrims have traveled across Europe to walk a sacred path in Northern Spain known as the Camino de Santiago de Compostela. They travel to pray at the tomb of St. James, one of the twelve apostles of Jesus of Nazareth. But now, scholars are exploring the possibility that the Camino may have been a sacred path long before the Christian Age, and new science is questioning whether or not the physical remnants at the tomb are in fact those of James.
