The magnetogram shows that the wooden construction elements of rampart II are quite different from those in Enclosure I (rampart I/A-B), although rampart II can also be divided into two longitudinal packets (see red markings).
The magnetogram shows concentrations of pits, and large rectangular houses (about 20 or 25 x 30m) possibly forming an urban scheme with lanes orientated along rampart II.
