The Camino de Santiago (Latin: Peregrinatio Compostellana, lit. 'Pilgrimage of Compostela'; Galician: O Camiño de Santiago), or the Way of St. James in English, is a network of pilgrims' ways or pilgrimages leading to the shrine of the apostle James in the cathedral of Santiago de Compostela in Galicia in northwestern Spain, where tradition holds that the remains of the apostle are buried. Pilgrims follow its routes as a form of spiritual path or retreat for their spiritual growth. It is also popular with hikers, cyclists, and organized tour groups.
Created and established in the beginning of the 9th century following the discovery of the relics of Saint James the Great, the Way of St. James became a major pilgrimage route of medieval Christianity from the 10th century onwards. Following the end of the Granada War in 1492, under the reign of the Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile, Pope Alexander VI officially declared the Camino de Santiago to be one of the "three great pilgrimages of Christendom", along with Jerusalem and the Via Francigena to Rome.
