Across the plains to Thuburbo Maius, a Roman city lying untouched amidst
the fields, in a plain surrounded by distant hills and mountains - a
particularly beautiful setting. Zaghouan’s Nymphaeum was built by order of
Hadrian at the source of the spring which feeds the great aqueduct of
Carthage. Part of the aqueduct channel is still visible as it heads off down
the hill on a remarkably steep gradient, to be carried on arches over the
valley of the Oued Meliane, and then on to Carthage - a total distance of 56
miles.
