قلعة حلب
Qal'at Dawsar was mentioned in 1040/41 when the Fatimid governor of Syria Anushtakin al-Dizbari was on a campaign in the area. At an unspecified point afterward it came into the possession of a certain Ja'bar ibn Sabiq, a member of the tribe of Banu Numayr or Banu Qushayr. He was killed there in 1071/72. It developed a reputation for being a haven for Bedouin highwaymen from the two tribes. In 1086 it was conquered by the Seljuks under Malik-Shah I, who granted it to the Uqaylid commander of the Citadel of Aleppo, Salim ibn Malik ibn Badran, as compensation for his surrender of Aleppo. The castle may have been built by the Numayr, but more likely its construction occurred under Salim.
