Quick primer on this Camino: The Camino Primitivo is the oldest of the Camino pilgrimage routes. In the 9th Century, the hermit, Paio, had a dream that angels led him to the remains of Saint James in a field where Santiago de Compostela is now.
The King of Spain at the time, Alfonso II, took a pilgrimage from the capital city, Oviedo, to confirm that the remains were indeed those of Saint James. Satisfied that they were, he ordered a modest church to be built around the tomb.
The Camino Primitivo loosely follows that original pilgrimage route from Alfonso II.
