Hazor expanding. The meeting point of the tenth- and ninth-century walls in Area M is shown in this photo. The tenth-century wall, which encompassed the western half of the tell, runs from south (left) to north (right) and then turns toward the west (top). The ninth-century wall extends from this corner of the tenth-century wall toward the east (bottom). The tenth-century casemate consists of parallel stone walls connected by thinner, internal walls that form rooms or casemates that could be used for storage or could be filled in for defensive purposes. By contrast the wall built around the eastern half of the tell in the ninth century is a solid wall.
