History
Carthaginian and Aghlabid eras
Present-day Sfax was founded by the
Aghlabids in AD849 on the site of the town of
Taparura. The modern city has also grown to cover some other ancient settlements, most notably
Thenae in its southern suburb of
Thyna.
Almohad era
By the end of the 10th century, Sfax had become an independent
city-state

Almohads, and was briefly occupied by European forces again, this time by the Spanish, in the 16th century, before falling into

Barbary piracy, prompting an unsuccessful invasion by

in 1185.
Al-Idrisi, in the 12th century, described Sfax as:
The city of Sfax is an ancient and thriving city with many markets and extensive buildings. It is surrounded by a stone wall with fortified iron-plated gates. Along its walls, there are well-constructed watchtowers for guarding. Its markets are lively, and its people drink from cisterns. Fine fruits of astonishing variety are brought to it from the city of Gabès in sufficient quantities, making them abundant and inexpensive. A significant amount of fish is caught there, large in size and plentiful in number, mostly captured using enclosures set up in stagnant waters through various clever methods. Its main agricultural products are olives and olive oil, which are of a unique quality not found elsewhere. The city has a harbor in stagnant waters. In summary, it is one of the most distinguished cities, and its inhabitants possess pride and dignity. The great King Roger conquered it in the year 543 AH 148 CE It remains inhabited today, though not as prosperous in architecture, markets, and trade as it was in ancient times.
Hafsid era
Abou Yahya Abou Bekr finally re-established
Hafsid unity and recaptured
Kerkennah from the Christians in 1335. The peace returned to the country was only disturbed by rare episodes, the most lasting of which began with the price of Sfax by the dissident brothers, Ahmed and Abdelmalèk ben Makki.
Towards 1370, following the arrival of Caliph Abdul-Abbas, Sfax returned under the Hafsid era.
After more than three centuries, which had seen the preponderance of the Hafsids, the conflict between the
Turks and the
Spaniards

precipitated the fall of their dynasty. In 1534, the privateer Barberousse entered Tunis, proclaimed the decline of the Hafsids and effortlessly reunited the towns of the coast, among them the town of Sfax.
Husseinid era
The founder of the new dynasty, Hussein, gave the country unquestionable economic prosperity. In Sfax, the mosque is enlarged, which regains its original extent; the new mihrâb is dated 1758, the work was completed in 1783.
The ramparts were restored and two large reservoirs were built to supplement the Nasriah cisterns. In 1776, the southern suburb of the city, the Frankish quarter, was built, reserved for Jews and Christians, a major place of maritime trade, but which was also to serve as a buffer against sea attacks, which were still to be feared. The eventuality was not long in coming, the Venetians bombarding Sfax four times in the space of two years (1785–86). A large fort was built during the siege to flank Borj Ennar; it was demolished after the last war.
Around 1830, the Frankish quarter was surrounded by a wall and in 1860 the city had a post office and telegraph. In 1876, the telegraph clerk made a plan of the city and told us about a signal tower built a century earlier and of which we have lost track.

Topography
The topography of the governorate of Sfax tilts regularly from the west to the coast and local presents small hills and mountain ranges in the form of elongated draâs.
Relief
Sfax is characterized by a monotonous, low and slightly uneven relief. The altitude y rarely exceed 250 m, especially in the center-west of the governorate (Draâ Lahirech, 269 m; Djebel Chebka, 255 m). Most of the study site extends over wide plains not exceeding the 150 m above sea level, including a low coastal strip about 15 km wide and having an average altitude of 20 m.
Hydrography
The monotonous character, low and not very rugged of the topography largely determined the characteristics hydrographic in the governorate of Sfax. Indeed, the rivers are numerous, shallow and rarely reaches the sea. The hills and small mountain ranges of the center-west present a hydrographic hairline dense and relatively deep compared to the coastal strip. Like a few exoreic rivers (wadi Agareb, wadi Laâchech, wadi El Maleh), most of the Wadis are endorheic, leading to closed depressions of the sebkhas and garâas type. Depending on their morpho-structural conditions, these closed depressions take the form of basins synclinal (Menzel Chaker and Hancha regions) or the form of sebkhas and garâas (Noual, Bou Jmal, Mchiguigue, Karafita... etc.).

Originally, the medina had only two doors:
Bab Jebli, also known as Bab Dhahraoui (northern door), and
Bab Diwan or Bab Bahr (the sea door). Yet, in the 20th century and because of the economic development and the huge increase of the population, new doors had to be created to reduce the flow from these two main doors such as
