We do not know what type of construction these towers would have taken. We have seen in the past that “tower” would appear to be related to the Mesoamerican stepped pyramid, but that is not necessarily the case here. The shape of the pyramid places the top further from the wall, and that would not fit the need of this type of defensive tower. It would make more sense if these towers were constructed of wood. Of course that would also explain why there are no specific remnants of this type of defensive tower. The understanding of the existence of a palisade on top of the earthen mound is based upon the evidence of the remaining postholes, not because the timbers were found. There is currently no mention in the literature of this type of tower, but if it were made of wood, that would not be surprising.
