Festivities of invierno de Muel Activity · Muel, Campo de Cariñena, Zaragoza Image of Muel, not of the place itself. Muel's winter festival is held in a village where Francisco de Goya frescoed the pendentives of the ermita de la Virgen de la Fuente in 1772, and which preserves a Roman dam over the Huerva built to supply Caesaraugusta. Its pottery, mostly Morisco, was interrupted for decades after the expulsion decree of Felipe III. Photo: Vikyto (CC BY-SA 3.0) What to see and do in Muel
