The Via de la Plata stretches across Spain from Seville to Santiago, moving up the western peninsula and through centuries of pilgrim history. It’s one of the routes that allows you to obtain the Compostela (certificate of pilgrimage) when you walk from (at least) Ourense to Santiago.
As well as being known as the Via de la Plata, or Silver Way, the route is sometimes called the Camino Mozárabe or Mozarabic Way of St James. The name of Via de la Plata doesn’t refer to actual silver, but is thought to be derived from the Latin word ‘Lapidata’, meaning stone road, or possibly the word ‘Balatta’, meaning road, in Arabic.
