Abu Shama recorded that no wall remained standing after the 1170 CE earthquake struck the Crusader fortress of Crak des Chevaliers (also known as Hisn al-Akrad), adding that “its repairs occupied the Franks [aka the Crusaders] entirely.” Sibt ibn al-Jawzi similarly wrote that “Hisn al-Akrad — Crak des Chevaliers — collapsed, and no trace of its walls remained.”
