Wine Cellars and Cave Houses of Moyuela Curiosity · Moyuela, Campo de Belchite, Zaragoza Image of Moyuela, not of the place itself. Architecture carved into the rock: cave-houses and underground wine cellars that offered cheap shelter and good conservation for wine. Among them stand out the so-called Cuevas de Valtierra, which were home to the village's first settlers and are today in poor condition. Photo: Ecelan (CC BY-SA 3.0) What to see and do in Moyuela
