Gea de Albarracin is a village in the Sierra de Albarracin up along the banks of the river Guadalaviar. The geography of Gea is clearly determined by its past. Perhaps the most significant landmark is its aqueduct of Roman origin (an artificial canal, which compose the rock-cut tunnels), who came from Albarracin and reached Cella with the intention of supplying water to the plain of Jiloca. This fascinating civil construction came to be 18 miles, and its usefulness disappeared in the twelfth century, when the great artesian well of River Cella was discovered, whose flow satisfied the needs for which the canal was built.
