Dominated by El Castillo (Temple of Kukulcán), Chichén Itzá blends Maya and Toltec elements—feathered serpents, colonnades, and the sacred cenote. The equinox serpent‑shadow phenomenon, ballcourt reliefs, and observatory architecture attract intense visitation managed by set circuits and conservation works.
El Castillo’s stepped pyramid, the Great Ballcourt, and the Temple of the Warriors showcase ritual, astronomy, and militaristic motifs.
Sinkholes (cenotes) structured sacred geography and supply; offerings from the Sacred Cenote attest to long ritual use.
Platform protection, guardrails, and stone consolidation respond to heavy foot traffic and tropical weathering.
