Roman calzada of the western peninsular that linked the city of Augusta ( Astorga ) with Emérita Augusta (Merida). The Arabs called this road al-balat, cobbled, which led to silver, by transforming into deaf the sound "b" of balat, the opposite of what has happened in the normal evolution of our language. Antonio de Nebrija in the early sixteenth century he already called it : Argentea dicitur vulgo . Over time the silver road became a tourist and cultural route also used by pilgrims of the Camino de Santiago.
