Gurza was also the seat of an ancient episcopal see of the Roman Catholic Church,[3] survives as a titular bishopric.

It was in the reign of the Aghlabid dynasty that the nucleus of the city was founded, in the place known as El Ksar, which consists of a very small city surrounded by a very high rampart with a door Unique on the eastern face leading to the market place.

The economy of Kalâa Kebira therefore relies mainly on agriculture.
