The pilgrimage to Santiago de Compostela has been an important event for European Catholics ever since the custom began in the 11th century. During the Middle Ages, its importance increased and pilgrims came from far-flung parts of Europe. In France, they took four principal routes to get to the road leading into Spain, and over the centuries those routes became the setting for some of the greatest achievements in mediaeval art and architecture. This book takes the modern reader along each of those four roads - from Paris, Vezelay, Arles and Le Puy - and charts the most celebrated buildings, monuments and art works to be found there today. The book concludes with the Spanish road which leads directly to the object of the pilgrimage: the great cathedral of Santiago de Compostela.
