Mills of the Río Frío Monument · Valdemanco del Esteras, Valle de Alcudia, Ciudad Real Image of Valdemanco del Esteras, not of the place itself. The mills of the Río Frío, documented since 1575, gave rise to Valdemanco del Esteras: the village was born when a group of millers and beekeepers decided to settle beside them, on the banks of the river. Today only their ruins remain, witness to the town's first settlement. Photo: 19Tarrestnom65 (CC BY-SA 4.0) What to see and do in Valdemanco del Esteras
