Edzna Archaeological Zone

Occupied from around 400 BC and reaching its peak between 600 and 900 AD, Edzna was the dominant Maya city of the western Chenes plain, controlling the region through one of the largest hydraulic systems built anywhere in the ancient Maya world. Its engineers cut roughly 25 km of canals, reservoirs and moats to capture and store seasonal floodwater in an area with no permanent rivers, a system that also served defensive and agricultural functions and supported a population estimated in the tens of thousands at the city's height. The site's centrepiece, the Edificio de los Cinco Pisos, rises five storeys in a single structure that combines pyramid and palace functions, with rooms built into each level rather than a solid pyramidal core, a design distinct from the temple-topped pyramids more typical elsewhere in the Maya lowlands. Nearby, the Templo de los Mascarones preserves stucco masks representing the sun god in its morning and afternoon aspects, among the best-preserved examples of Maya architectural sculpture in the region. Excavation and consolidation have been ongoing since the mid-20th century under Mexican archaeological authorities, focusing on stabilising the Edificio de los Cinco Pisos and the surrounding plazas while leaving much of the wider hydraulic system unexcavated. Interpretation at the site follows the chronological development of the urban core, from its early canal-building phase through its Late Classic architectural peak.
