The castle probably stood on the location of an earlier Roman site, the name of which has not yet been identified, although
Caeciliana has been suggested. The oldest reference to Qal'at Najm in Arabic texts is
Jisr Manbij, while the current name came only into popular use in the 12th century CE. According to one text,
Caliph Uthman had a bridge constructed over the Euphrates at Jisr Manbij. Following the conquest of the region by the
Umayyads, the castle was controlled by the
Hamdanids and the
Mirdasid dynasty, before passing into the hands of the nomadic tribe of the
Banu Numayr. until at least 1120. Control then shifted to the
Zengid dynasty under Nur ad-Din, ruler of Aleppo and the son of
Zengi. Nur ad-Din had the castle restored. In 1820, an Arab warlord sought refuge in the castle, which was subsequently besieged and damaged by
Ottoman forces. On 1 June 2016, during the
Syrian Civil War, the
SDF captured Qal'at Najm from
ISIS. == Description ==
