The Camino de Santiago (Latin: Peregrinatio Compostellana, lit. 'Pilgrimage of Compostela'; Galician: O Camiño de Santiago; Spanish: El Camino de Santiagocode: spa promoted to code: es ; Portuguese: O Caminho de Santiagocode: por promoted to code: pt ), 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. In 1987, the Camino, which encompasses several routes in Spain, France, and Portugal, was declared the first Cultural Route of the Council of Europe. Since 2013, the Camino has attracted more than 200,000 pilgrims each year, with an annual growth rate of more than 10 percent. Pilgrims come mainly on foot and often from nearby cities, requiring several days of walking to reach Santiago. The French Way gathers two-thirds of the walkers, but other minor routes are experiencing a growth in popularity. The French Way and the Northern routes in Spain were inscribed on the UNESCO World Heritage List, followed by the routes in France in 1998, because of their historical significance for Christianity as a major pilgrimage route and their testimony to the exchange of ideas and cultures across the routes.
