Mill of Ricla Monument · Ricla, Valdejalón, Zaragoza Image of Ricla, not of the place itself. The mill of Ricla stands beside the Jalón, in a town with a rock-set castle turned into a palace, whose rammed-earth walls can still be seen on the calle de la Cruz, and which holds the Feria de la Cereza y el Ajo Tierno every year.
