Lake of Tunis

The Lake of Tunis (Arabic: البحيرة El Buhayra‎, French: Lac de Tunis) is a natural lagoon located between the Tunisian capital city of Tunis and the Gulf of Tunis (Mediterranean Sea). The lake covers a total of 37 square kilometres, in contrast to its size its depth is very shallow. It was once the natural harbour of Tunis.


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. The northern lake includes the island of Chikly, once home to a Spanish stronghold, and now (since 1993) a nature reserve.

Due to the lake's continuing aggradation during the 19th century, the French colonial forces traversed the lake with a 10 km long, 450 m wide, and 6 m deep canal.


Recently, the Tunisian government and Sama Dubai of the UAE (led by Dubai Governor Mohammed bin Rashid Al Maktoum) have joint-ventured an investment agreement to develop the southern shore of the lake into a new commercial, residential and touristic center in Tunisia and the Mediterranean. Total costs of the investment, considered the biggest in Tunisia's history, will be around $18 billion USD. The project should be ready in the next 10 to 15 years.
