Archaeoastronomy of Teotihuacan and Tenochtitlan

Abstract

In this paper, we discuss the astronomical orientations in the city plans of Teotihuacan and Tenochtitlan. Mesoamerica exhibits much archaeoastronomy and these two sites are rich examples. Both exhibit alignments for solar horizon events that are integral in deliberate calendrical systems. The logic of these systems is shown, and this demonstrates that these cities were carefully planned with astronomical knowledge.
