سيدي بوسعيد
The Tunis-Carthage connection was very important to the Romans, as it meant control over the fertile hinterland. The Romans therefore built a dam through the lake. The dam is used today as an expressway for automobiles and railway connecting Tunis to the harbour, La Goulette, and the coastal cities of Carthage, Sidi Bou Said, and La Marsa.
