A tzompantli was a purpose built rack, typically wooden poles set on a stone platform, on which the skulls of sacrificial victims were displayed in public, strung horizontally in rows through holes drilled in the temple bones or otherwise mounted for standing exhibition. The great tzompantli of Tenochtitlan stood adjacent to the Templo Mayor, and Spanish conquistador accounts, later regarded as exaggerated in exact numbers but confirmed in kind by archaeology, described tens of thousands of skulls arranged on it. Excavations beginning in 2015 near Mexico City's cathedral uncovered a large tower and platform of human skulls, plastered and in some cases painted, belonging to the actual Huei Tzompantli structure, confirming the rack's existence, general form and use of both male and female, and adult and child, remains, complicating earlier assumptions that its contents were exclusively adult male war captives. The structure functioned publicly, displaying the outcome of sacrifice as a visible statement of religious and imperial power rather than concealing it.

Contested or Appropriated Modern UseScale and composition of the skull racks' contents 2 The tzompantli, the Aztec skull rack displaying the remains of sacrificial victims, was described by early Spanish conquest-era chroniclers with skull counts running into the tens of thousands. Eduardo Matos Moctezuma's The Great Temple of the Aztecs (1988), reporting the archaeological excavation of the Templo Mayor precinct where the great skull rack, the Huei Tzompantli, stood, records that modern archaeologists treat the chroniclers' tens-of-thousands figures as inflated for rhetorical effect, written to justify the conquest to a Spanish audience, while the excavated physical evidence independently confirms the structure held a genuinely large number of human remains. That excavated evidence also revised the assumed population: the remains include women and children alongside adult men, not only adult male war captives as had long been assumed from the colonial narrative alone. The method is archaeological, recovering and analysing the skeletal remains directly. Because excavation both confirms the general scale and revises the specific demographic assumption, the contested figure remains an active subject of ongoing analysis. Use

Power Made Visible, Not Concealed
The tzompantli was built to be seen. Skulls were typically defleshed, then had holes drilled through both temples so wooden poles could pass through in horizontal rows, stacking dozens or hundreds of skulls into a single visible wall facing the plaza in front of the Templo Mayor, one of the most heavily trafficked public spaces in Tenochtitlan.
Sixteenth century Spanish accounts, including those gathered by Sahagun and by the conquistador Andres de Tapia, describe the sight as deliberately calculated to communicate the scale of Mexica military success and religious devotion together, since each skull represented both a defeated enemy and a completed sacrificial offering. The rack stood in full public view rather than in a restricted temple precinct, a choice that distinguishes it from many other sacred objects on this site whose handling was reserved to priests, and its placement directly adjacent to the empire's primary religious and political center made it, in effect, a running public monument to the outcome of Aztec warfare and worship combined. Smaller tzompantli associated with regional temples elsewhere in the Aztec empire, and among neighboring Mesoamerican cultures who adopted the practice, suggest the structure's public display function was not unique to the imperial capital alone.
What the 2015 Excavation Confirmed and Complicated
For centuries the tzompantli of Tenochtitlan was known only from colonial written description and a handful of earlier partial finds, leaving open how much of the Spanish account was eyewitness record and how much was rhetorical exaggeration meant to justify conquest to a European audience. That changed when Mexico's National Institute of Anthropology and History, excavating near the Metropolitan Cathedral beginning in 2015, uncovered a circular tower and adjoining platform built substantially from human skulls, plastered over and in places painted, identified as part of the actual Huei Tzompantli, the great skull rack described in colonial sources.
Osteological analysis of the recovered remains complicated the long standing assumption that the rack held only adult male war captives, since the tower included the skulls of women and at least a few children, suggesting a broader range of sacrificial victims, or a broader range of circumstances under which skulls entered the structure, than colonial and earlier scholarly accounts had assumed. The find is treated by archaeologists as confirmation that the structure existed substantially as described, while its exact total scale and the demographic breakdown of its contents remain subjects of ongoing excavation and analysis rather than settled figures.
