Shrine of la Virgen de Castrotierra Monument · Riego de la Vega, La Bañeza, León Image of Riego de la Vega, not of the place itself. A hermitage in the outlying village of Castrotierra de la Valduerna which holds an image of the Virgin venerated throughout the diocese. In years of drought the carving is carried in supplication to Astorga cathedral, some seventeen kilometres away. Photo: Jaime Calatayud (CC BY-SA 4.0) What to see and do in Riego de la Vega
