Tenayuca is an archeological Mesoamerican site in Mexico which dates back to the Aztec and Chichimec civilisations. It was probably founded in the thirtenth century and was later absorbed in to the Aztec empire, probably around the mid fifteenth century. The city was still occupied when the conquistadors arrived, though the settlement fell to ruin after the collapse of Aztec power in the region.

Today the site of Tenayuca is nestled right in the heart of the modern municipality of Tlalnepantla de Baz in Greater Mexico City and consists of a vast Mesoamerican pyramid structure which dominates the site. The ruins are located almost surreally among a throng of shops, small cafes, haidressers and houses and city life busstles around this immovamoble monolith at a million miles an hour.
