This mosque was built in 1534. It bore the name of a slave converted to Islam Safar bin Abdullah, then, the name Safar became Safir. In 1826-27 (1242), the last Dey of Algiers, Hussein Pasha had it rebuilt.
Architecturally, the prayer hall has a cruciform plan with a large central culminating dome, sharing the same principle as other Ottoman mosques of Algiers, namely:
Jami' Ali Bitshin,
Jami' Ketchaoua, and
Jami' al-Jadid.
The minaret has an octagonal base and is located at the south corner, adjacent to the qibla wall.
