Beni Mazar’s original name, in the distant past, was ‘Bab Mazar,’ meaning ‘Door of Mazar’ because it was the entrance for people visiting Bahnasa, which is famous for its sanctuaries. 

There are many Islamic and Christian monuments in Beni Mazar, the most famous of which are the dome of Seven Girls, who participated in the wars to conquer Bahnasa; the Tree of the Virgin Mary, under whose shade the baby Jesus, his mother Mary, and Joseph the carpenter sat when they sought refuge in Egypt; and the shrines of Jaafar and Ali, the children of 'Oqail Ibn Abi Taleb. 

There is also the dome of Takroury (Abdullah Al-Takroury), one of the Moroccan princes who visited Bahnasa; the monument to Lady Khawla Bint Al-Aazwar, from the Fatimid era, who was the sister of Derar Ibn Al-Aazwar; and the dome of Abu-Samra (Abdullah Ibn Abu-Samra Al-Bahnasy).

In addition to these are the shrine of Prince Ziad Ibn Al-Harith Ibn Abu Sufian Ibn Abd El-Muttaleb; the monument to Uthman Ibn Affan; the Minaret of Sidi Abu Samra Ibn Zain Al-Aabedin Ibn Al-Hussain; and the monument to Muhammad Ibn Abu Zir Al-Ghafary.

Other Islamic monuments include the dome of Muhammad Ibn Abu Abd Al-Rahman Ibn Abu Bakr Al-Sadeeq; the monument to Sidi Ali Al-Jamam, the judge of Bahnasa province and one of the Maliki Imams during that time; and the Mosque of Al-Hassan Al-Saleh Ibn Zain Al-Aabedin Ibn Al-Hussain Ibn Ali Ibn Abu Talib.
