The Dike of Nezahualcoyotl: Aztec Flood Control Genius

Long before the Spanish arrived, Tenochtitlan faced a constant threat: the brackish waters of Lake Texcoco. In the 1440s, after a devastating flood, the tlatoani Moctezuma I turned to an unlikely ally — the poet-king Nezahualcoyotl of Texcoco. Together they engineered the Albarradón de Nezahualcoyotl, a nine-mile dike that separated freshwater from saltwater, protected the city, and created a controlled aquatic environment for chinampas. This episode dives into the construction, the ingenious design using wattle and daub, the labor of thousands of macehualtin, and the political alliance that made it possible. We also explore the dike's role in the 1519 Spanish siege and its rediscovery in the 20th century. How did a pre-Columbian megaproject shape the fate of an empire — and why did Cortés himself later repair it? #AlbarradónDeNezahualcoyotl #Nezahualcoyotl #MoctezumaI #LakeTexcoco #Tenochtitlan #AztecEngineering #chinampas #macehualtin #tlatoani #Cortés #FloodControl #Mesoamerica #AztecEmpire #History #FexingoHistory #AncientEngineering #MexicoCity #Hydrology Keep every episode free: buymeacoffee.com/fexingo
