Qastun is identified as the ancient Aramean town of Qattun or "Qatan" of the Iron Age. It is listed in an Assyrian text from Kultepe. The site of the ancient town is about 16 hectares and is spread between the two parts of Qastun i.e. Qastun al-Gharbi and Qastun al-Sharqi. The latter sits on an elevation 25 meters above the surrounding territory alongside the Qastun River.[3]
The Syrian geographer Yaqut al-Hamawi visited Qastun during Ayyubid rule in 1225, noting that it was "a fortress that was in the district of Ar Ruj in the Halab (Aleppo) Province."[4] During the conflict between the Mamluks (successors to the Ayyubids) and a Mongol-Armenian alliance, an elite Mongol force of some 1,500 soldiers raided Qastun in 1271, massacring and plundering its Turkmen inhabitants.[5] In the Spring of 1298, a Mamluk army led by al-Muzaffar III Mahmud, the Ayyubid vassal of Hama, launched a campaign to conquer Armenian-held Cilicia, but only reached Qastun, before being recalled to Aleppo.[6]
Modern era
When the nearby Zeyzoun Dam collapsed in June 2002, floods destroyed and damaged hundreds of houses in Qastun and the nearby villages of Qarqur, al-Ziyarah and Zeizoun.[7]
According to the Syrian Observatory for Human Rights, a man was shot dead at a security checkpoint in Qastun on 4 September 2012, during the ongoing Syrian civil war.[8] According to an opposition activist from Hama, 25 children were killed by shooting or stabbing in Qastun and nearby al-Aqbayr on 6 June 2012 by pro-government forces.[9]
