The Silent Exodus of Angkor: What Lidar Reveals About the World's Largest City's Abandonment

For centuries, the abandonment of Angkor, the vast capital of the Khmer Empire, was a mystery shrouded in jungle. The narrative blamed a sudden Siamese invasion. But cutting-edge laser archaeology has rewritten the story, revealing a sprawling megacity and a far more gradual, and revealing, end. This episode explores the revelations of airborne lidar, which stripped back the forest canopy to expose Angkor's true scale: a thousand-square-kilometer engineered landscape of canals, reservoirs, and suburbs. The data points not to a sudden sack, but to a slow-motion failure of the city's monumental hydraulic system. We examine how decades of drought intersected with over-engineering, siltation, and maintenance collapse, making the city unlivable. You will see how the most advanced archaeological tools are solving history's greatest puzzles. The fall of Angkor becomes a cautionary tale about environmental management and the vulnerability of even the most sophisticated infrastructure to climate shifts. Sometimes, civilization's greatest works are its own tomb. #AngkorWat #KhmerEmpire #LidarArchaeology #HydraulicEmpire #ClimateChange #MegaCity #UrbanCollapse Hosted by Ibnul Jaif Farabi.
