Zaghouan
Mountain water source — Roman aqueducts and the Temple of Waters.
Zaghouan is built against a 1,295 m massif that towers over the eastern plain. Its limestone springs supplied Roman Carthage through the Zaghouan-to-Carthage aqueduct, the longest in the Roman Empire.
The most striking ruin is the Temple of Waters at the foot of the mountain — a semicircular nymphaeum that captured the spring water at its source.
Today Zaghouan is a hiking and weekend-getaway destination, with cool air, olive groves and several boutique guesthouses in restored Andalusian villages like Takrouna and Zriba El Olia.
