Templo Mayor is the excavated remains of the main temple of the Aztec capital Tenochtitlan — the pyramid that stood at the centre of the empire and was the site of human sacrifices, astronomical observations, and the political ceremonies that held the Aztec world together. The temple was destroyed by the Spanish in 1521 and buried under the colonial city, and it wasn't rediscovered until 1978 when electrical workers stumbled upon a massive stone disc depicting the dismembered goddess Coyolxauhqui.
The excavation that followed revealed seven layers of construction — each Aztec ruler built a new temple over the previous one, like Russian nesting dolls in stone — and the ruins now sit in an open pit adjacent to the Metropolitan Cathedral, creating a visual collision between the Aztec and Spanish worlds that is the defining image of Mexico City's layered identity. You look down from street level into the foundations of a civilisation that the street was built to erase.
The adjacent museum is excellent — one of the best archaeological museums in Mexico, displaying over 7,000 objects recovered from the excavation, including the Coyolxauhqui Stone, sacrificial knives, offerings of jade and gold, and the remains of the tzompantli (skull rack) that once displayed the heads of sacrificial victims. The museum's presentation is matter-of-fact about the violence of Aztec religion while contextualising it within a sophisticated civilisation that built aqueducts, schools, and botanical gardens alongside its sacrificial altars.
