Benvenisti, 2000, p. 302: 'The arbitrary designation of any especially massive structure as "Crusader" verges on the absurd in the case of Jidin Castle (on Kibbutz Yehiam), which was built by Sheikh Dahr al-'Omar al-Zaidani . Within this large fortress are remnants of a small Crusader fort; nevertheless the Israelis refer to Yehiam Castle (as Dahr al-'Omar's fortress is called today) as "a Crusader castle that was destroyed at the time of the Muslim conquest and partially reconstructed by Dahr al-'Omar."
