The granary of the rubión wheat Curiosity · Palaciosrubios, Tierra de Peñaranda, Salamanca Image of Palaciosrubios, not of the place itself. Before the Renaissance, palacio designated the cilla or grain store, and rubio in the Middle Ages was equivalent to red, as well as naming a variety of wheat, the rubión; the place name would therefore allude to the store of rubión wheat or to the red brick cilla.
