Hundreds of hidden structures of ancient civilization have been discovered beneath the Amazon

A groundbreaking archaeological discovery has revealed hundreds of hidden structures beneath the dense rainforests of southern Amazonia, offering new insights into the ancient civilization of Aquiry. The findings, made possible through advanced LiDAR technology, suggest that this long-lost society was far more extensive than previously believed, with its influence spanning vast areas of the region during its peak around 200 AD. The research, conducted over a large portion of the Amazonian basin, uncovered nearly 4,300 square kilometers of terrain that had been concealed under centuries of vegetation. Among these newly identified features were 432 earthworks, including 396 previously unknown ones. These structures, which include geometric formations and wide roads connecting them, indicate a highly organized society capable of large-scale engineering projects. According to Dr. Martti Pärssinen of the University of Helsinki, the discovery marks a turning point in understanding the scale and complexity of Aquiry’s urban planning and social organization. Historically, the civilization of Aquiry is known to have flourished between approximately 600 BC and 850 AD, shaping the landscape of southwestern Amazonia. Its inhabitants carved intricate geometric patterns into the land, creating a network of earthen mounds and pathways that connected key sites within the state of Acre in Brazil. These constructions, often enclosed by deep channels, served as gathering spaces for political and ceremonial functions. However, much of their history remains shrouded in mystery due to the lack of written records and the eventual disappearance of their settlements. The recent study, which analyzed data collected via airborne laser scanning, has significantly expanded the known extent of Aquiry's influence. Researchers estimate that the civilization could have covered up to 183,000 square kilometers at its height, potentially supporting populations ranging from 1.2 million to three million individuals. This suggests that the area once inhabited by Aquiry would have looked vastly different from today, characterized by open clearings, or “clearings,” where communities lived, farmed, celebrated, and gathered. At the heart of many of these clearings stood massive geometric earthworks linked by broad and narrow roads. Pärssinen described the magnitude of the find as unprecedented, noting that the number of geoglyphs and other earthworks discovered on less than three percent of the Amazon Basin was staggering. He emphasized that the results challenge previous assumptions about the density and intensity of human activity in the region, suggesting that other parts of the Amazon might have been similarly transformed by ancient societies. Despite the remarkable revelations, several questions remain unanswered. One of the most pressing concerns is the fate of Aquiry after its decline around 850 AD. What caused the sudden collapse of such a sophisticated society? And why did its cities and infrastructure vanish so completely from historical record? These mysteries continue to fuel further investigation into the environmental, social, and cultural factors that shaped the rise and fall of this ancient civilization.
