Note: Cahors is the main city of Quercy with a harbor for boat-traffic. In 1200 the city had not yet developed into the important mercantile center it would become in the 13th century. Cahors contains many roman ruins and Christian buildings including the Cathedral of Saint Étienne, Church of Saint Urcisse, Church of Saint Barthélemy, Chapel of Saint Martin, and many basilicas. Cahors 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.
