Being surrounded by a wall, the town had an access gate and large open areas inside which may have served as sites for trading or check point for the imported goods. Several houses were clustered outside the town which may have acted as temporary resting places for travelers and merchants as they awaited clearance or purchase of their goods. An extensive brick wall surrounded the lower part of the town and the area occupied by the citadel. This served to protect the town from flooding during high tides.
Several huge square towers and bastions were also set up in the citadel. The houses were also located in the same neighborhood as the other facilities which give the picture of a tightly-knit community (Possehl, 2000).
