The Discovery of the “Lost Cities” of Amazon

In 1925, British explorer Percy Fawcett vanished ¹ in the Amazon rainforest, leaving a compelling mystery that has captivated the world for nearly a century.

Fawcett, an experienced adventurer, embarked on his eighth expedition with a singular goal: to uncover the ruins of a fabled city he called “Z.”

This quest was fueled by centuries-old rumors of grand cities hidden deep within the Amazon, a notion dismissed by many experts who believed the harsh rainforest environment could never support such civilizations.

The Myth of El Dorado

The legend of El Dorado ², a city of unimaginable wealth, has captivated adventurers and conquerors since the 16th century. This myth, rooted in South American folklore, ensnared even Sir Walter Raleigh.

The tale began with the Spanish explorers in the early 16th century, who heard stories of a tribe in the Andes mountains.

Their chieftain, covered in gold dust during a ritual at Lake Guatavita, was known as “El Dorado,” the gilded one. This ceremony, where gold and jewels were cast into the lake to appease an underwater god, ignited the European imagination.

Despite numerous expeditions, including Raleigh’s tragic quest that led to his son’s death and his execution, the golden city remained elusive.

The Spaniards found Lake Guatavita and attempted to drain it in 1545, uncovering some gold but not the legendary riches they had hoped for.

Fawcett’s Unyielding Pursuit & Dismissal of an Ancient Urban Landscape

Percy Harrison Fawcett’s extensive explorations in the Amazon were driven by a conviction that contradicted the prevailing beliefs of his time.

Despite his extensive knowledge of the region and reputation as a skilled mapmaker and decorated war hero, Fawcett’s expeditions in the western and southern Amazon yielded no tangible evidence of the advanced civilizations reported by early European explorers.

His encounters with indigenous peoples, who lived in simple villages, seemed to reinforce the then-dominant view that the Amazon was too inhospitable for large, complex societies. This, combined with prevailing theories about the indigenous people’s supposed lack of sophistication and the infertile nature of Amazonian soil, led many to dismiss the possibility of ancient urban settlements in the region.

Fawcett’s unwavering belief in the existence of the City of Z ³, however, propelled him forward, challenging the scientific consensus of his era and setting the stage for one of the 20th century’s greatest exploration mysteries.

Terra Preta

Decades after Percy Fawcett’s disappearance, a significant breakthrough occurred with the discovery of terra preta, or black earth. This fertile soil, found extensively in the Amazon, especially along rivers, was rich in nutrients, challenging the long-held belief that the Amazon’s soil was too poor to sustain significant populations.

Terra preta ⁴ was created by an ancient Amazonian civilization’s bio-waste and excreta treatment, converting 10% of the region’s formerly infertile soil. Remarkably, these soils remain fertile even 500 years after the civilization’s disappearance.

The discovery of terra preta not only hinted at the possibility of large-scale agriculture but also indicated a highly efficient and simple sanitation system that integrated waste management and agriculture.

This revelation has reshaped our understanding of the Amazon’s ecological history, suggesting that the region once supported a complex, sustainable civilization capable of transforming and enriching its environment.

Rediscovering the Amazon’s Urban Past

In the 1990s, Dr. Michael Heckenberger’s team made a groundbreaking discovery in the upper Xingu region of the southern Amazon, Brazil. They uncovered extensive evidence of a sophisticated network of urban communities, challenging the long-held view of an “untouched” Amazon.

The findings included remnants of large roads, bridges, and plazas, suggesting a highly organized, grid-like pattern of settlements. These roads, some as wide as modern four-lane highways, linked settlements every two to three miles along an extensive grid, indicating a level of planning and engineering previously unimagined in the Amazon.

The discovery of 19 settlements, with at least four major residential centers built around large circular plazas, revealed a civilization that dramatically altered its landscape. This civilization, ancestors of the modern-day Xinguanos, managed their environment meticulously, transforming vast areas into cultivated lands or park-like forests.

A Cradle of Ancient Civilizations

The recent discoveries in the Amazon have led to a radical rethinking of its history. The evidence of large settlements, sophisticated urban planning, and extensive networks suggests that the Amazon was once home to millions
