Chichén Itzá

East of the Nunnery, the Puuc-style Akab-Dzib is thought by some archaeologists to be the most ancient structure excavated here. The central chambers date from the 2nd century. The name means ‘Obscure Writing’ in Maya and refers to the south-side annex door, whose lintel depicts a priest with a vase etched with hieroglyphics that have yet to be successfully translated.
