Tetzcotzinco: Ancient hydraulic site of Nezahualcóyotl

Tetzcotzinco, located in the hills of Texcoco, represents a significant example of pre-Hispanic hydraulic engineering and architecture in central Mexico. Associated with the ruler Nezahualcóyotl, the site served as a complex system of gardens, canals, and aqueducts designed to manage water from mountain springs.

The ancient Acolhua people utilized a network of canals and embankments to transport water, using materials such as sand, lime, tezontle gravel, and stucco for waterproofing. The site is notable for its integration with the natural landscape, featuring rooms, pillars, and sculptural elements carved directly into the rock of the Metécatl Hill.

According to the National Institute of Anthropology and History (INAH), the site is open to the public from Tuesday to Sunday, between 10:00 and 16:00, with free admission. Visitors are advised to prepare for rugged terrain and follow established routes to preserve the archaeological integrity of the area.
