The Camino Francés is an 800-km showcase of brilliant church and cathedral architecture, documenting the history of this art form from early pre-Romanesque roots through to more contemporary expressions. The highlights are almost certainly the great Romanesque and Gothic works, though the ultimate target, Santiago de Compostela's cathedral, is most closely associated with its Baroque facade. In this episode, Kathleen Ashley, the author of Being a Pilgrim: Art and Ritual on the Medieval Routes to Santiago, explains the basics of church architecture and describes how pilgrims--past and present--can best approach their visit. In addition, Karl Otto, a pilgrim from Chicago, reflects on his walk on the Camino Francés.
