Traces of a lost civilization? Researchers find hundreds of mysterious structures in the Amazon

Archaeologists have discovered hundreds of mysterious structures located in the Amazon, which are believed to have been built over 2000 years ago. These mysterious structures were still hidden for centuries from the Amazon and show that the Amazon is not as untouched as we believed in the past.

Fascinating ancient structures, most likely, were built by an unknown civilization.

The traditional idea shared by many historians is that before the arrival of the Spaniards and Portuguese in the fifteenth century, and unlike traditional Andes history, the Amazon region did not have any advanced civilizations. But, given the fact that deforestation has revealed most of the hidden secrets of this area, scientists are convinced that the advanced civilization inhabited this region in the distant past. There are numerous aerial and satellite images, a complex network of structures, roads and even, perhaps, settlements, which until now remained hidden under the impenetrable layer of the Amazon.

These remarkable earthworks were discovered due to rapid deforestation, which allowed experts to identify more than 450 massive geoglyphs in the rainforest.

Although their size and complexity have caught archaeologists by surprise, experts are still unsure of their purpose, but some authors suggest that massive fences can be used sporadically as places for ritual gatherings.

According to, the structures are unlikely to be villages, as archaeologists have extracted very few artifacts during excavations. In addition, the location of structures implies the presence of protective structures.

Mass structures, similar to Stonehenge, occupy about 13,000 square kilometers in Acre, in the western Brazilian Amazon.

Scientists from Britain and Brazil said that these structures prove that Amazon is not intact, as we believed in the past.

The fact that these places are hidden for centuries under mature tropical forests really challenges the idea that the Amazon forests are untouched ecosystems, said Dr. Jennifer Watling, a graduate student at the Museum of Archeology and Ethnography of the University of São Paulo.

We immediately wanted to know whether the region was already wooded when geoglyphs were built, and to what extent people worked on the landscape to build these excavations.

Researchers managed to look into the past, having restored 6000 years of vegetation and fire history in the vicinity of two archaeological sites, using modern methods, revealing HEAVY changes in the ancient culture that inhabited this region.

Scientists say that the ancients modified the bamboo forests for millennia, building small temporary glades to erect these mysterious structures.

Experts found that instead of burning large parts of the forest, the ancients were able to transform their environment, focusing on economically valuable tree species such as palm trees, creating a kind of prehistoric supermarket of useful forest products.

Dr. Watling said: Despite the huge number and density of geographic sites in the region, we can be sure that the Acres forests have never been cleared so extensively, not for long, as it has been in recent years.

Our evidence that Amazonian forests are managed by indigenous peoples long before European contact should not be used as an excuse for the destructive, unsustainable land use practiced today. Instead, it should emphasize the ingenuity of past livelihood regimes that have not led to forest degradation and the importance of indigenous knowledge for finding more sustainable land use alternatives.
