ABSTRACT
Teotihuacan's basic denotation as a place of significance stems from the manner in which its urban artefacts are interlocked with the landscape. A similar relationship exists between the Sun Pyramid and a large mountain in the southeast. From the Plaza of the Moon, the pyramid and this mountain seem to overlap perfectly. The avenue connected the pyramid's massive structure with an older monument, which may have been the most important shrine before the demographic explosion. The end of Teotihuacan's hegemony may have affected other Mesoamerican sites, when the collapse of a wide network exchange articulated with Monte Albn and Tikal, among others, triggered alliances between competing sites. The Aztec advanced a new layer of connotation to include the mythical site as a foundation to their novel worldview. In the next couple of centuries, the ancient ruins of Teotihuacan remained a silent witness to the fall of Mesoamerican traditions.
