Pilgrims traveling on the Camino de Santiago today pass by reminders of medieval monasteries that once played an essential role in the pilgrimage. While some monastic communities operate on the lands of their medieval ancestors, others have been abandoned, and only ruins remain, shells of affluent institutions with little hint of the tremendous wealth and sprawling domains that they once controlled. This episode explores the political and spiritual landscape that contributed to the development of monasteries along the Camino. It also discusses some of the most influential monastic orders, their patrons, way of life, and the services offered to passing pilgrims.
