Arcade romaine

This surviving arcade is a remnant of the Roman aqueduct of Zaghouan, which once carried water more than 132 kilometres from the springs of Djebel Zaghouan to the North African metropolis of Carthage. Built most likely under Emperor Hadrian in the 2nd century AD, it ranked among the longest aqueducts in the entire Roman Empire and sustained a city that may have housed half a million people at its peak. The weathered brick arches now stand as open-air ruins, illustrating Roman engineering at monumental scale — the structure relied on precise gradient calculations across rugged terrain rather than any pumping mechanism. The site rewards visitors interested in ancient hydraulics and the physical legacy of Roman North Africa.
