The goal of the research on the Ziggurat of Borsippa was to attempt to find out with the greatest precision possible the appearance of the graduated tower, the phases of construction, how the construction technology changed in the course of time and which static problems were solved. However, the answer to all these questions is only possible when we attempt to understand better the thought processes of the ancient Babylonians: why was such a huge building constructed and what religious ideas were behind it? It is, therefore, a particular goal for the excavation of the Ziggurat to come a step closer to explaining the function of a graduated tower. The archaeologist's great dependence on the cooperation of the scientist is illustrated in the contribution.
