Whether you're climbing up to Puerto del Palo or descending from it, it's worth stopping along the way to enjoy this inhospitable village, with some of its houses and hamlets uninhabited. It evokes a mix of emotions in me because the beauty of the place and its surroundings is indelible... as is the sadness of seeing these enclaves disappearing.

The ruins of the hospital of Fonfaraón are the remains of an ancient hospital that served as a shelter and refuge for pilgrims on the Camino Primitivo, the oldest route to Santiago de Compostela. The hospital was located on a mountain range called Sierra de Fonfaraón, in the municipality of Allande, Asturias, Spain. It was one of the four hospitals that existed on this alternative route, known as the Route of the Hospitals, which was used by pilgrims when the weather conditions made it impossible to cross the lower valleys.
