The Roman aqueduct from Gea to Albarracín Historical milestone · Gea de Albarracín, Sierra de Albarracín, Teruel The Roman aqueduct of Albarracín-Cella, also known as that of Albarracín-Gea-Cella, runs some 25 kilometres through the districts of Albarracín, Gea de Albarracín and Cella, in the Sierra de Albarracín (Teruel). Surviving from the 1st century is the section cut into the rock which, in the district of Gea, overcame very difficult terrain to bring water from the Guadalaviar river to the area around Albarracín and, beyond that, to the settlement that once existed at what is now Cella; its construction required work on several fronts simultaneously. It is one of the most important public hydraulic works of Roman Aragon, together with the Muel dam and the Los Bañales aqueduct, and it was declared Bien de Interés Cultural (Spain's highest level of heritage protection) with monument status in 2002. siglo I Photo: Diego Delso (CC BY-SA 3.0) What to see and do in Gea de Albarracín
