Zaghouan, Tunisia
Zaghouan is a historic town in northern Tunisia, located approximately 37 miles (60 km) south of Tunis. It is best known for its exceptional Roman hydraulic engineering, serving as the primary water source for ancient Carthage and modern Tunis.
Zaghouan is widely identified with the Roman city of Zica, which was part of the Province of Africa Proconsularis, one of the most important Roman administrative regions in North Africa.
Why Zaghouan Is Historically Significant
Zaghouan’s importance in antiquity stems from its natural mountain spring at Djebel Zaghouan, which enabled the Romans to construct one of the most ambitious water-supply systems in the Roman Empire.
This system includes:
- A monumental Roman Water Temple
- An extensive aqueduct network
- Continuous water delivery from antiquity to the present day
Roman Water Temple (Temple des Eaux)
The water supply for Carthage originated at Djebel Zaghouan, where a powerful spring emerges from the mountain.
At this source, the Romans built the Temple des Eaux, a monumental Water Temple and Fountain constructed directly over the spring. The structure served both religious and engineering purposes, marking the official starting point of the aqueduct system that carried water to Carthage.
The Zaghouan Roman Aqueduct
The Zaghouan Roman Aqueduct is one of the longest known Aqueducts in the Roman Empire, extending approximately 82 miles (132 km).
Construction Timeline
- Construction began during the reign of Hadrian (117–138 CE)
- Completed in 162 CE to supply water for the Baths of Antonius in Carthage
Engineering Features
- Combination of underground channels and above-ground arcades
- Designed to maintain consistent water flow across long distances
- One of the most advanced hydraulic systems of the Roman world
Surviving Remains and Modern Use
Several portions of the aqueduct remain visible today:
- Standing columns near Mohammedia, approximately 2 miles (3 km) south of Zaghouan
- Additional sections near Uthina (Oudna)
In 1859, large sections of the aqueduct were restored. Notably, the system continues to supply water to Tunis today, making it one of the longest continuously used water infrastructures in history.
