Using advanced LiDAR technology, researchers have peered through the dense canopy of the Colombian Amazon to find a previously unknown complex of stone structures. The site, located on a remote plateau in the Guaviare region, consists of twelve large circular ritual plazas connected by a network of raised stone causeways, hidden for two millennia under tropical vegetation.
Initial ground surveys suggest the site was a major cultural center dating back to 100 CE. The concentric wall patterns and solar-aligned gateways indicate a sophisticated understanding of celestial movements by these early mountain dwellers. This discovery significantly expands the known extent of complex pre-Columbian societies in the northern Amazonian highlands.
