In 1033, most of the walls constructed by Eudocia were destroyed by an earthquake. They had to be rebuilt by the Fatimids, who left out the southernmost parts that had been previously included: Mount Zion with its churches, and the southeastern hill (the City of David) with the Jewish neighborhoods which stood south of the Temple Mount. In preparation for the expected Crusader siege of 1099, the walls were strengthened yet again but to little avail. The conquest brought some destruction followed by reconstruction, as did the reconquest by Saladin in 1187. In 1202 to 1212 Saladin's nephew, Al-Malik al-Mu'azzam 'Isa, ordered the reconstruction of the city walls, but later on, in 1219, he reconsidered the situation after most of the watchtowers had been built and had the walls torn down, mainly because he feared that the Crusaders would benefit of the fortifications if they managed to reconquer the city. For the next three centuries, the city remained without protective walls, the Temple Mount/Haram ash-Sharif and the citadel then being the only well-fortified areas.
