Photograph of the Chichen Itza tzompantli. This kind of structure was a low platform on which wooden racks stood for the display of the skulls of enemies. The name of this structure comes from that of equivalent structures in Náhuatl-speaking Central Mexico. Tzompantlis began appearing in the Maya area during the Early Postclassic as yet another indication of heavy Central Mexican influence. As with other structures in Chichen, this one stands out as being one of the largest tzompantli ever found anywhere.
