Researchers Report Unusual Pre‑Hispanic Structure in Western Mexico

Archaeologists working in the state of Jalisco say they have uncovered a pre‑Hispanic stone platform that they describe as having “unprecedented” features. The site, located near the town of Tequila, consists of a rectangular foundation built from large limestone blocks arranged in a pattern that does not match known architectural styles of the region’s known cultures, such as the Teotihuacan or the later Aztec. The team, led by Dr. María López of the National Institute of Anthropology and History (INAH), says the structure measures roughly 12 metres by 8 metres and includes a series of shallow depressions that they interpret as possible ritual basins.

The researchers base their claims on a limited excavation that revealed no associated ceramics, organic material, or radiocarbon‑dateable samples. As a result, they have not been able to assign a precise date to the construction. Dr. López notes that the lack of typical decorative motifs and the unusual stone arrangement suggest the possibility of an undocumented local tradition, but she also acknowledges that the site could be a later colonial modification or a natural rock formation that was misidentified as human‑made.

The discovery was reported in a press release from INAH and covered by local media. Independent experts have not yet examined the site, and some scholars caution that without stratigraphic context or datable artifacts, the claim of an “unprecedented” pre‑Hispanic architecture remains provisional. Further systematic excavation and analysis will be required to confirm the structure’s age and cultural affiliation.
