The overlooked corners inside

• Eagle's House

  From the site's walkways, this L-shaped building looks unassuming — yet it was the most private space in the entire Templo Mayor precinct. It takes its name from the finds inside: eagle heads along the outer walls, sculptures and ritual objects tied to the Mexica Eagle Warriors (*cuāuhpipiltin*). But the building's real weight lies elsewhere. Before ascending to power, each newly chosen *huey tlatoani* — the supreme ruler — came here first to fast, withdraw, and prepare. The entire arc of imperial rule began in this room. What looks like a side chamber was in fact the threshold of an empire.

• Tlaloc Shrine

  The two summit shrines crown the main pyramid at its highest point — the north one dedicated to Tlaloc, god of rain, and the south to Huitzilopochtli, god of war. Tlaloc's shrine belongs to the world of water: the rainy season, the summer solstice, nighttime, earth and agriculture, rendered in blue. In front of the entrance stands a painted Chac Mool — a reclining stone figure colored blue, red, white, and black — serving both as a sacrificial altar and as intermediary between worshipper and deity. The doorposts are carved with Tlaloc's goggle eyes, framed by alternating black-and-white vertical bands evoking falling rain; the roof crenellations take the form of jars, conch shells, and clouds — all symbols of water. What you can see today is the Phase II structure (c. 1390 CE), beneath whose floor Offering 40 was buried.

• Huitzilopochtli Shrine

  The south summit shrine — dedicated to Huitzilopochtli, patron war god of the Mexica — stands paired with Tlaloc's shrine to the north, together forming the heart of Templo Mayor. This side corresponds to the dry season, the winter solstice, daytime, sky, and fire, expressed in red ochre. In front of the entrance stands a *techcatl*, a volcanic-stone sacrificial block; excavators found a cache of ritual blades beneath it. Inside, a stone bench running north–south once held a cult statue; high on the walls, L-shaped crenellations contrast sharply with the water-shaped ones on the opposite shrine. The chronicler Andrés de Tapia, who accompanied the conquistadors, described a colossal statue of Coatlicue — Huitzilopochtli's mother — standing on the summit, adorned with a belt of golden serpents and a necklace of golden human hearts. What survives today is the Phase II structure (c. 1390 CE, before c. 1428), one of the best-preserved sections of the whole site.

• Templo Mayor Archaeological Zone

  The Templo Mayor archaeological zone covers 1.2 hectares in the heart of Mexico City's historic center, steps from the Zócalo. What you see above ground — the twin-towered main pyramid, three smaller north shrines, the Altar Tzompantli (skull rack), two red-painted Xochipilli shrines, the House of Eagles, and remnants of the Sacred Precinct's enclosure wall — maps the surviving outline of the Aztec Empire's ritual center. Its rediscovery began on February 21, 1978, when workers from the Central Electricity Company, digging a cable trench, struck the massive stone disk of Coyolxauhqui, the moon goddess. Archaeologist Eduardo Matos Moctezuma immediately launched the Templo Mayor Project; the first excavation season (1978–1982) recovered more than 7,000 artifacts. Ancient sources describe the Sacred Precinct as containing 78 structures; archaeological investigation has so far confirmed around 36 of them.

• Coyolxauhqui Stone

  At the foot of the staircase leading up to Huitzilopochtli's shrine, a great circular stone lies flat on the ground. Carved in high relief, it shows Coyolxauhqui, goddess of the moon — dismembered, her limbs and head separated from her torso. This is not damage. It is myth frozen in stone. Legend tells that the moment Huitzilopochtli was born, he cut his sister Coyolxauhqui to pieces for having led a plot to kill their mother, and flung the fragments down the mountain. The pyramid's summit, where offerings were made, represented that mythic mountain. When a sacrificial victim was pushed down the stairs, the body fell here, onto this stone — re-enacting the myth, time after time. The stone is the landing place.
