Approximately 100 m of this outer enclosure wall are rather well preserved to a height of 3 m. The architectural survey finished the documentation of 60 m and pursued a section on top of the outer enclosure wall to investigate the junction of two segments. Built in alternate panels of concave and convex courses of mud brick, the structural analysis of the walls allows to assume, that the stability could be increased in conditions of permanent weight. Based on these observations it can be concluded that this construction technique brought essential structural benefits. ...
