A breakthrough LiDAR survey conducted in the dense jungles of the Darién Gap has identified a previously unknown urban complex belonging to the Gran Coclé culture. Spanning over 150 hectares, the site features a massive fortified citadel with concentric stone ramparts and over 400 circular residential foundations. This discovery suggests a much higher degree of social organization and territorial defense than previously attributed to the pre-Columbian cultures of the Panamanian isthmus.
Archaeologists believe the citadel served as a strategic maritime-terrestrial trade hub, controlling the flow of gold and exotic feathers between the Pacific coast and the Caribbean. The mapping revealed a sophisticated system of paved causeways connecting the central plaza to several outlying agricultural terraces, indicating a permanent, year-round population supported by intensive cultivation of root crops and maize.
