But what marks the Pd most is the construction of defences in four successive phases. Originally the defences were constructed towards the beginning of the Pd and consisted of massive mud ramparts, 10·12 m wide at the base and more than 8 m high with magnificent gateways, guard-rooms, ancillary passages and corner towers. In the second phase the clay rampart being susceptible to erosion was reinforced by adding a thick layer of gravel on its top. The third phase is marked by the erection of two brick walls, 8 m apart, on the top of the gravel layer with fillings of mud and debris in between. Finally, a collapsed revetment wall was renovated with a battered exterior.
