Kafr Kanna was conquered by the Crusaders in 1099. During this period, Ali of Herat wrote that one could see the Maqam of Jonas, and also the grave of his son, at Kafr Kanna. This was repeated by Yaqut al-Hamawi, although he only wrote of the tomb as being that of Jonas' father. The name Casale Robert was used by Franks, beside variations on the Arab name. In August 1254 Julian the lord of Sidon sold it to the Knights Hospitaller.
