Who was Al-Mustansir bi-Allah?
Al-Mustansir bi-Allah ruled for more than half a century, through periods of strength and severe crisis that affected both the state and the capital. Late in his reign he turned to Badr al-Jamali, who reorganised the government and began a major defensive project to enlarge Cairo and surround it with new stone walls.
Bab al-Futuh, Bab al-Nasr and Bab Zuweila belong to this period. They are among the clearest surviving markers of the boundaries of Fatimid Cairo after its expansion in the 5th century AH.
How did they shape Cairo?
The fortification project under al-Mustansir was a turning point in the shape of the city. The new wall did not just replace Jawhar's; it widened Cairo and brought in areas and buildings that had been outside the old boundary. The new gates became fixed points on the city's routes for centuries.
That is why al-Mustansir's mark on Cairo shows in the city's structure and boundaries more than in any single religious building bearing his name.

Where to see their legacy today
The best route is Bab al-Nasr, then Bab al-Futuh, then down al-Muizz Street to Bab Zuweila – the closest living picture of the boundaries that were redrawn late in al-Mustansir's reign.
