In the 1^st century A.D., two long aqueducts were built to supply the city with water. The first, known as Aqua Augusta, was fed by the Gaià river and was approximately 50 km long. The second was fed by the Francolí river and was some 15 km long. The most spectacular surviving stretch belongs to the second aqueduct and consists of a 217-metre segment that stands 26 metres tall at its highest point and bridges a ravine. It was built from large ashlars stacked without mortar to form two tiers of arches. It is popularly known as the Pont del Diable (Devil’s Bridge) or the “Les Ferreres” Aqueduct.
