The main mosque on this cidadel used to be known as Masjid al-Kaff but today is just known as the Grand Mosque. It has the white dome directly in the middle of the above photo. Its Mihrab Qibla has an inscription stating that it was completely renovated in 1719 - 1720 A.D. under the supervision of Abu Bakr Ben Mulla Omar.So it is impossible to determine what the original Qibla directoin was.
