What is “a pilgrimage route” often supported by?

The story behind the answer

In the Middle Ages, the care of travelers was a religious duty, so pilgrims found beds, bread, and basic medical aid at abbeys, priories, and charitable hospitals (xenodochia). These institutions maintained waystations along major routes, guided travelers with posted signs or relic shrines, and funded the work through tithes, endowments, and alms—fulfilling the Christian “works of mercy.”

This network shaped famous paths like the Camino de Santiago and the Via Francigena, where “albergues” and hospitals dotted the road. The Knights Hospitaller grew from a Jerusalem hospital serving pilgrims, later becoming a major military‑charitable order. Monastic communities also kept bridges and ferries, offered letters of introduction, and provided spiritual support. Modern tourism agencies and hotels are a much later invention; medieval civic authorities had limited resources, so religious houses were the dependable backbone of long-distance travel.
