Cholula

Cholula was not built. It was grown. Successive cultures added layer upon layer over more than a thousand years, each enclosing what came before rather than replacing it. The result is not a single monument but a geological record of belief — a structure that expanded the way a tree expands, by adding rings.

The base measures 450 by 450 meters. Nearly half a kilometer on each side. Its volume exceeds Giza's by roughly forty percent. It stands only 66 meters tall — far shorter than Giza's 146 — but its footprint is so enormous that, from a distance, it does not read as architecture. It reads as topography. The Nahuatl name is not poetic exaggeration. It is a precise description.

Archaeologists have identified at least four major construction stages and nine or more minor modifications. The earliest phases date to the Late Formative period, beginning around the 3rd century BCE. The final major expansion concluded somewhere around the 8th or 9th century CE. That is roughly a thousand years of continuous monumental construction. No comparable building campaign exists anywhere else on Earth.

What each new phase did not do is erase the previous one. The older structures were sealed and covered — entombed inside the growing mass of the new construction. This practice, common across Mesoamerica, implies a relationship to architecture that European building traditions do not have. A building was not a static object. It was a living entity, periodically renewed through burial and rebirth. To build upon the pyramid was to continue it. Each generation did not inherit a monument. It inherited an obligation.

The pyramid's stylistic evolution maps the shifting politics of Mesoamerica like nothing else does. Its early phases show unmistakable affinities with Teotihuacan, the great metropolis to the northwest. The talud-tablero profile — a sloping base panel beneath a vertical framed panel — appears in Cholula's earlier layers. This either reflects direct cultural exchange, political subordination, or a shared architectural vocabulary. The question has not been settled.

When Teotihuacan collapsed around the 7th century CE, Cholula's construction phases shifted. Influences from the Gulf Coast — particularly from El Tajín in present-day Veracruz — became visible in decorative motifs, ceramic styles, and architectural details. The pyramid was not just a religious site. It was a political instrument, its form reorienting to reflect new alliances.

Scholar Geoffrey McCafferty, one of the foremost researchers of Cholula's archaeology, has argued that the successive layers of construction should be read as successive claims to legitimacy. Each new culture wrapped its authority around the sacred core of its predecessors. The pyramid was not merely a temple. It was a statement — a deliberate assertion that whoever built upon this mound was heir to everything built before.

This is what makes Cholula structurally different from Giza. Giza was one ruler's declaration, built within a human lifetime, frozen at completion. Cholula was an argument that lasted a thousand years, made by cultures who disagreed on almost everything except the holiness of this particular ground.

The pyramid was dedicated to Quetzalcoatl — the feathered serpent. Not merely a deity. A civilizing principle. Quetzalcoatl carried wind, learning, agriculture, the morning star, and the breath of life. That Cholula was his primary cult center in the Postclassic period tells you something specific: this structure was understood as the earthly seat of one of Mesoamerica's most fundamental forces.

The mythological traditions surrounding the pyramid's construction go further. One prominent legend names Xelhua — a giant who survived a great flood and attempted to construct an enormous mound to reach the heavens. The gods, angered by the act of ascent, hurled fire upon the builders and halted the work. The story is strikingly close to the biblical Tower of Babel. Scholars disagree on why. The options are genuine cross-cultural archetypes, post-conquest contamination of indigenous narratives by Christian missionaries, or a real catastrophic event encoded in multiple mythological traditions independently.

The Aztecs, inheriting older narratives about the site, attributed the pyramid's construction to giants fleeing a great deluge. This fits the broader Mesoamerican cosmological framework of successive world ages, each ending in cataclysm. Flood narratives appear across the ancient world with a consistency that demands explanation. Whether that explanation is psychological, catastrophic, or something else is not yet agreed upon.

What is not in dispute: the mythology and the architecture at Cholula were never separate domains. The pyramid enacted the cosmic drama of ascent, destruction, and renewal in stone and earth. To build upon it was to enter the story. To worship inside it was to become a character in a myth that had been running for centuries before your arrival.

Modern excavation began in 1931, when Mexican architect Ignacio Marquina initiated a systematic tunneling program into the pyramid's interior. Over the following decades, approximately eight kilometers of tunnels were cut through the structure. What they found had been sealed for centuries.

The Patio of the Altars — Patio de los Altares — sits on the pyramid's south side. It contains carved stone altars and stelae decorated with serpents and iconographic elements associated with Quetzalcoatl. Burials found in and around the patio span multiple periods. The site continued to function as sacred ground long after major construction ended. People did not stop returning. They kept burying their dead there, leaving offerings, treating the mound as holy long past the point when anyone was adding new stone to it.

The murals inside the tunnels are among the most significant finds. Known as the Bebedores — the Drinkers — they depict ritual drinking scenes, possibly of pulque, the fermented agave beverage central to Mesoamerican ceremonial life. These polychrome paintings are not solemn. They show communal celebration, ritual intoxication, the human body in states of ecstatic release. In Mesoamerican thought, these states facilitated contact with the divine. The pyramid was not only a place of worship. It was a place of communion — in the oldest sense of that word.

In 2023, researcher Mark Milligan reported new discoveries at the site, adding to the known construction sequence. Each find confirms the same thing: the eight kilometers of tunnels, vast as they are, represent a fraction of the total interior. The pyramid is mostly unexcavated. What murals remain sealed inside its unexplored mass? What tombs? What artifacts? The honest answer is that we do not know.

In October 1519, Hernán Cortés perpetrated a massacre in Cholula that killed thousands. It was strategic terror — designed to break the surrounding populations before the march on Tenochtitlan. One of the most important pilgrimage centers in Mesoamerica was devastated in days.

The spiritual conquest followed the military one. The Iglesia de Nuestra Señora de los Remedios — the Church of Our Lady of Remedies — was constructed on the pyramid's summit, with most accounts placing its founding around 1594. The placement was not accidental. Constructing Christian churches on indigenous sacred sites was standard colonial practice across Latin America. The intention was legibility: Christianity stands here now. The old gods are beneath us, in every sense.

What the colonizers did not recognize — and may never have — is that they were continuing the very tradition they believed they were ending. For a thousand years, successive cultures had built upon this mound. Each new layer claimed the spiritual authority of what came before. The Spanish church was, structurally speaking, the fifth major construction phase. Another group wrapping its theology around the ancient core. Another claim to legitimacy through vertical accumulation.

The indigenous populations of Cholula may well have understood this intuitively. The mountain endured. The names of the gods changed. The impulse to ascend did not.

Today the church's yellow-and-white facade gleams against the backdrop of Popocatépetl and Iztaccíhuatl — the snow-capped volcanoes that ancient mythologies already encoded with stories of love, loss, and catastrophic transformation. The colonial church does not cancel the pyramid beneath it. The pyramid does not invalidate the centuries of Catholic devotion above. They coexist, uneasily and precisely, as layers of the same argument about what this ground means.

When Graham Hancock featured Cholula in episode 2 of his Netflix series Ancient Apocalypse, he used its scale and its flood mythology to support his longstanding argument: that an advanced, now-lost civilization seeded architectural and astronomical knowledge across the ancient world. Cholula's immensity, its parallel flood narratives, its apparent connections to other pyramid-building cultures — in Hancock's framing, these became circumstantial evidence for a forgotten origin.

The archaeological response was direct. Kayleigh, a historian and content creator, published a detailed critique of the episode, challenging what she identified as selective use of evidence, questionable measurements, and mischaracterization of professional archaeologists. The mainstream scholarly position is equally direct: the similarities between pyramid-building cultures are best explained by convergent cultural evolution. Independent societies arriving at similar architectural solutions because they faced similar structural problems — how to build tall with available materials — and made similar astronomical observations.

This position has accumulated evidence behind it. Cholula's construction chronology is documented through stratigraphy, ceramic analysis, and radiocarbon dating. The pyramid's development from a modest Late Formative platform to a colossal multi-phase structure is consistent with gradual indigenous innovation. There is no archaeological evidence at the site of technologies or knowledge systems that fall outside the known framework of Mesoamerican cultural development.

The questions Hancock raises are not all illegitimate. Why do flood myths appear with such consistency across unconnected cultures? Why do pyramid forms recur in Egypt, Mesoamerica, Mesopotamia, and Southeast Asia? What might the archaeological record have lost when sea levels rose dramatically at the end of the last Ice Age, submerging coastal settlements that could have held critical evidence?

These are real questions. They demand methodological rigor, not wishful thinking. The evidence at Cholula supports a narrative of indigenous Mesoamerican achievement — completely, without qualification. The broader questions about cultural transmission and shared mythological motifs remain open, and their openness is not an invitation to fill the gap with speculation. It is an invitation to look harder at what we have.

Visitors to Cholula today can enter the excavated tunnel system. The passages are narrow. The weight of millions of tons of earth and stone presses from every direction. The air is cool and carries the mineral scent of deep time. Emerging from the tunnels into the Patio of the Altars — carved stelae, open sky — feels like surfacing from something older than language.

The ascent to the summit church is different. From the top, the modern city of San Pedro Cholula spreads in every direction. The city famously has a church for every day of the year, according to local legend — over 365 churches visible from the pyramid's crown, their domes and towers cataloguing four centuries of Catholic presence. On clear days, Popocatépetl and Iztaccíhuatl frame the horizon. The same peaks the pyramid's original builders saw. The same peaks their myths are still about.

The pyramid has not been restored in the way other Mesoamerican sites have. Its earthen covering remains largely intact. The full scale of the architecture stays hidden. This is either a form of protection or a form of neglect, depending on where you stand. The modern city has grown around and partly over the pyramid's base. Full excavation is not possible. The church cannot be moved. The people live there.

The site is managed as both an archaeological zone and a living community space. Festivals, markets, and religious celebrations continue to take place in the pyramid's shadow. The mountain absorbs them. It has absorbed everything placed upon it for two thousand years. There is no reason to believe it will stop.

Cholula commands a fraction of Giza's popular recognition. This gap is not explained by size — Cholula wins. Not by age — both are ancient. Not by complexity — Cholula's layered construction history is arguably more intricate than anything in Egypt.

The gap is explained by whose antiquity Western culture decided to inherit. Giza sits within a tradition that European scholarship claimed as its own predecessor. Mesoamerican civilizations were placed in a different category — encountered, conquered, and then studied from outside rather than from within a continuous tradition of admiration. The result is a hierarchy of ancient achievement that has more to do with the 16th century than with the 3rd century BCE.

The people of Cholula did not vanish when Cortés arrived. The indigenous communities of the Puebla region carry living traditions, languages, and cosmological frameworks that connect them — however transformed by five centuries of colonial pressure — to the builders of Tlachihualtepetl. Their relationship to the pyramid is not archival. It is present. Any honest reckoning with the site must include them, not as historical subjects but as people who currently live beside the largest pyramid on Earth and know what it is.

The builders of Tlachihualtepetl did not seek to create a single, perfect, eternal structure. They created a practice — of building upon building, layer upon layer, generation upon generation. The monument was not the finished product. The act of building was. The church on the summit is not an imposition on this logic. It is an inheritance of it. The question is not what the pyramid was. The question is what it is still becoming.
