Report summary,"The magnetometer survey detected high linear anomalies along the wall linking the Great Wall with the Qaleh. Interestingly, there are no high magnetic readings in the alignment of the Great Wall between these two junction walls at all. This suggests that either the Qaleh was included in the defensive system from the start, via a loop-shaped extension to the north, and the Great Wall never built between the start and end point of the loop – or that it was, following or during a later inclusion of the Qaleh in the defensive system, systematically robbed out. To our surprise, a high magnetic anomaly appears to surround the Qaleh at the bottom of the slope. This anomaly partially overlaps with a scatter of bricks fragments at the bottom of the slope. Especially in the north-east, the brick fragments form a distinct band, even if in places the anomaly extends well beyond the modern brick scatter; this may be the result of the built-up of recent alluvial deposits at the bottom of the slope. The brick scatter suggests that we are probably not dealing with a silted-up ditch filled with magnetic material. It is worth noting that there are comparatively few fired brick fragments from the top of the Qaleh and the higher slope (except for the southern side), but a dense cluster at the bottom of the slope. By contrast, the scatter of the pottery sherds over the top of the Qaleh and the upper and lower parts of the slope seems much more even. These observations suggest that we are not dealing with the collapsed remains of a fired brick wall at the edge of the plateau. Furthermore, it seems unlikely that such a remarkably regular anomaly could have formed at the bottom of a steep slope as a result of the collapse of a brick wall far above. A robbed-out fired-brick wall near the bottom of the slope seems the most likely interpretation of the anomaly, even if the possibility of the remains of a collapsed structure accumulating at the bottom of the slope cannot be entirely excluded.
