What happened
At the heart of Tenochtitlan's sacred precinct stood the Templo Mayor, called Hueteocalli by the Aztecs, a pyramid platform roughly 60 meters high topped by two side-by-side shrines reached by separate staircases. World History Encyclopedia describes the north shrine as dedicated to Tlaloc, god of rain, marked by steps painted blue and white for water, while the south shrine honored Huitzilopochtli, god of war and the sun, with steps painted red for blood and war. The Tlaloc temple aligned with the summer solstice, symbolic of the rainy season, while Huitzilopochtli's aligned with the winter solstice, marking the traditional start of the campaign season. Archaeologists working the site since Mexico City's Proyecto Templo Mayor began in 1978 have identified at least seven successive construction phases, each king rebuilding and enlarging the temple over the one before, meaning the structure the Spanish saw in 1519 encased generations of earlier temples inside it.
Why it matters
The dual shrine physically expressed the Aztec worldview that war and agricultural fertility were two faces of the same cosmic obligation, both requiring blood and offerings to keep functioning. The repeated rebuilding of the temple over two centuries also gives archaeologists a rare layered record of Aztec religious architecture and its changes over time, all preserved beneath modern Mexico City.
How we know
Ongoing excavation by Mexico's Instituto Nacional de Antropologia e Historia since 1978, combined with 16th-century eyewitness descriptions from Spanish chroniclers and the Florentine Codex, allows archaeologists to reconstruct the temple's several building phases and their religious functions.
