Note: Bazas was one of the pilgrimage sites on route to the Cathedral of Santiago de Compostela, home of the shrine dedicated to Saint James, the patron saint of Spain. The symbol of Saint James, the scalloped shell, became the primary symbol representing pilgrims. French pilgrimage routes to Compostela tend to follow old Roman roads, many of which continued to be utilized as primary roads of communication during the Middle Ages. Bazas is known to have been a walled town by the 5th century. Located in Bazas is the Cathedral of Saint-Jean-Baptiste, the Church of Notre-Dame, the Church of Saint-Martin, the Chapel of Saint-Martial, and the Priory of Saint-Vivien-outside-the-Walls.
