 Sultan Qalawun destroyed both castles so thoroughly that even the site of Batroun's citadel is lost from history.With Nephin (Enfeh) it was a different story, for here the Crusaders had performed one of the great engineering feats of the Middle Ages.They had cut off the peninsular fortress from Enfeh proper by cutting a great moat, at sea level, all the way across the peninsula, for over 100 yards, through the living rock, leaving only a small spur in the center at the south end to support the castle's drawbridge.
