The 2,500-Year-Old Secret Hidden Under the Amazon

In 1925, British explorer Percy Fawcett disappeared into the Amazon while searching for a legendary lost city he called “Z.” He was never found. For decades, many believed his search was based on an impossible dream. The Amazon rainforest was widely thought to be incapable of supporting the large, complex societies described in early historical accounts. But new archaeological discoveries began challenging that assumption. Using advanced technologies such as LiDAR, researchers have uncovered evidence of ancient settlements, geometric earthworks, roads, and carefully organized landscapes hidden beneath the forest canopy. From mysterious geoglyphs in Brazil to vast settlement networks in the Upper Xingu, Ecuador's Upano Valley, and Bolivia's Llanos de Mojos, these discoveries are changing how we understand the history of the Amazon. So, was Percy Fawcett wrong about the lost city he sought—or did his search point toward a much bigger historical truth? Discover the evidence, explore the mystery, and uncover the forgotten societies that once transformed the Amazon. Welcome to CIVORA — Where History Comes Alive.
