Archaeologists utilizing high-definition LiDAR (Light Detection and Ranging) have mapped a sprawling 1,500-year-old urban network hidden beneath the dense jungle of the High Valleys of Northern Laos. Dubbed the 'City of the Silver-Herons' due to the recurring avian motifs found on ceremonial stone gateways, the site encompasses over 40 square kilometers of elevated stone plazas, interconnected by a sophisticated system of stone-paved causeways and defensive moats.
The city represents a previously unknown civilization that appears to have specialized in high-altitude agriculture and the trade of precious mountain minerals. Excavations at the central administrative core have revealed massive granaries and evidence of advanced hydraulic engineering used to manage seasonal monsoon waters. Dr. Viengkeo Souksavatdy, lead researcher for the project, noted that the discovery fundamentally shifts our understanding of the demographic density and political complexity of pre-Angkorian Southeast Asia.
