Introduction to pilgrim road signs: The Pilgrimage Road to Santiago has been equipped with a large number of quite clear road signs since ancient times. These are sometimes stone tablets, sometimes wooden signs, and road signs marked with shells (legend has it that Saint Jacob was born a fisherman, so The shells have become the symbol of the entire pilgrimage route) and are the traces left by the pilgrims. You only need to follow such symbols all the way to reach the final destination of the pilgrimage, the Cathedral of Santiago the Apostle.
