The name El-Biar (الأبيار) means in Arabic "the wells" because of the multitude of wells available to this locality. The central square, Place Carnot during the French presence, named after Place Kennedy was designed in a "neo-Moorish" style before the 1930s. It includes the APC (Popular Municipal Assembly), the mosque (built between 1964 and 1966 by the architect Abderrahmane Bouchama) and the large post office (which dates from 1935).
