<P> The Neolithic wall was complemented by a stone tower built into it . The wall was possibly built in order to prevent floods and the tower used for ceremonial purposes but the height of the wall ( approximately 1.5 to 2 metres ( 4.9 to 6.6 ft ) thick and 3.7 to 5.2 metres ( 12 to 17 ft ) high , as well as that of the tower ( 8.5 metres ( 28 ft ) ) suggests a defensive purpose as well . Furthermore , the construction of such a project implies some sort of social organization , division of labour , and classes . Surrounding the wall was a ditch 8.2 metres ( 27 ft ) wide by 2.7 metres ( 9 ft ) deep , cut through solid bedrock with a circumference around the town of as much as 600 metres ( 2,000 ft ) . Kathleen Kenyon commented on the work involved in the construction of the ditch : `` The labor involved in excavating this ditch out of solid rock must have been tremendous . As we have discovered nothing in the way of heavy flint picks , one can only suppose that it was carried out with stone mauls , perhaps helped by splitting with fire and water . '' </P>
