The Teotihuacan Tunnel beneath the Temple of the Feathered Serpent

Record summary

A tunnel beneath the Temple of the Feathered Serpent at Teotihuacan was recognized and investigated in mid-century archaeological work, adding evidence for subterranean ritual architecture and the city’s ceremonial planning. Such passages were later connected in popular writing to hidden chambers, secret technologies or unexplained builders, but archaeological interpretations emphasize cosmology, caves and controlled access. This lead is useful for comparing architecture, excavation technique and ritual symbolism. Exact construction phases, contents and relationships to other Teotihuacan tunnels require consultation of excavation reports.
