Note: Saint-Martin-de-Londres is 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. Saint-Martin-de-Londres is on the east edge of a rocky plateau marking the boundary of the plain of Londres. An important historic site in Saint-Martin-de-Londres is the former priory church of Saint-Martin.
