Abstract: | The Metropolitan Cathedral of Mexico City has undergone alarmingly large differential settlings. An extensive geotechnical investigation programme was performed in its subsoil, as part of the studies required in an ongoing salvage project. The results of many of the soundings performed can be interpreted from the viewpoint of the archaeologist. This paper shows, based upon the framework provided by previous archaeological research performed in the cathedral, that the geotechnical investigations allow the unique opportunity of establishing hypotheses regarding the extent and distribution of some of the structures that existed in the ritual precinct of Tenochtitlan, as well as of its foundation. |
