La Mohammedia - Aqueduct of Hadrian

Two km/1.25mi south of the village of La Mohammedia are the remains of the Aqueduct of Hadrian, which runs alongside the road for a distance of some 5km/3mi. Built between A.D. 120 and 131 and borne on massive 20m/65ft high piers linked by arches, the aqueduct carried water to Carthage from Djebel Zaghouan (1,295m/4,249ft), the highest peak in the northern Dorsale, a distance of 90km/55mi. After the fall of Rome the aqueduct continued to be used and kept in repair by the Byzantines, the Fatimids and the Hafsids, but from the 14th century onwards it gradually fell into ruin.
