Sultan Abu Amr Othman (839-888 H/1435-1483 AD) ordered the construction of this zaouia on a lot where stood a lead-smelting workshop and offered it to Sheikh Abou al-Abbas Ahmed ibn Arous of whom he was a disciple. The holy man Sidi Ben Arous is also buried here. Currently the building is used as a public library and offices for associations dedicated to the preservation of the Koran. Recently the monument was damaged by a fire but it has been totally restored.
