Ancient ruins in the rainforest

Was the Amazon Rainforest Once Home to A Massive Lost Civilization?

(Read the article on one page)

There is a hill in the Amazon rainforest that stretches out over two acres of land. It is called Montegrande and, to look at it, it seems like nothing more than another hill. A particularly steep one perhaps, but nothing more than an overgrown mound of earth. For centuries, it was ignored, and, in time, as Peru’s cities and towns stretched further out in the Amazon, farmers even set up their homes on top of it.

Then they started to dig. As the farmers worked the land, they started to uncover sherds of old pots. These, they soon learned, were more than old utensils. These were relics of the past, and they were more than 1,000 years old.

Their homes became an archaeological site. In 2010, archaeologist Quirino Olivera and his team started digging into the Montegrande hill, and soon discovered what they were excavating wasn’t a hill at all. It was a massive pyramid, built by a forgotten civilization in the Amazon rainforest – and it was over 3,000 years old.

The Empty Amazon Theory

The pyramid at Montegrande changed everything. Here, for the first time, was hard proof that ancient civilizations had thrived in the Amazon rainforest.

Ancient civilizations had certainly flourished in South America, but, up until recently, it had been believed that the Amazon itself was a place few dared to tread for long. The few people who lived there in ancient times, archaeologists believed, were sparsely separated, nomadic people. They would wander from place to place, setting up the odd short-lived farm before moving on.

When the Spanish conquistadors arrived in South America, they wrote stories about massive towns in the Amazon full of farms and supporting whole fleets of boats – but there’d never been anything to back up what they were saying. Every piece of archaeological evidence we could find suggested that no one in the Amazon had stayed still long enough to build a home.

Discoveries like Montegrande, though, are changing the history of a nation. Now it’s believed that, at its peak, there may have been as a many as 5 million people living in the Amazon. They built civilizations and cultures that are completely forgotten to time. The only way we’ll ever know who these people were is by sifting through their bones.

A Forgotten Civilization

The people who built the Montegrande, the archaeologists have since learned, had an incredibly sophisticated society . They didn’t just build one pyramid and leave. They first built it in 1,000 BC, but they reworked it and rebuilt it at least eight times. Before their empire ended, they had lived in that one spot for more than a thousand years.

By the end, they were building six-foot (1.83-meter) walls to protect their people and setting up offices where rulers governed their people. They built a grid of homes across the riverbank, had an elaborate religion of their own, and were part of an elaborate trade network the stretched across modern Peru.

They have a whole millennium of history that’s only hinted at in their remains. What we know is only scraped together from their ruins, but the massive pyramids they left behind are enough to give an incredible glimpse into their religion.

The Spiral Temple

At the top of the mound is a spiral of rocks, coiled in the shape of a massive snake or, perhaps, in the swirl of the shell of a snail. You could walk along the spiral like you were making your way through a labyrinth. Every step would take you further down below the ground until you reached the center, forty feet (12.19 meters) below the first step.

At the center of the spiral, the people who once lived here burned fires. These were likely sacred fires, used for some religious purpose – and there’s reason to think it involved drugs.

Archaeologists have found snuff spoons and mortar grinders still holding the residue of hallucinogenic vilca seeds. These seeds didn’t grow where they lived – they were imported, and getting their hands on these things might just be the reason this civilization created such an elaborate trade network.


really interesting article, thank you, I have a question re:"The bones of the children appear to have been brutalized. A six-year-old is buried there with his pet guinea pig, while a young mother lies there with her newborn child, both decapitated."
Are you assuming the children were sacrificed or could they have stripped flesh from bones prior to burial as a number of other cultures have done? Human sacrifice doesn't quite fit with pet burial. Maybe they removed their heads after death to make them part of a wall or altar?
I seem to remember the Egyptians held deformed and sickly people in high regard as they saw them as messengers from the gods who could create perfection but would on occasion create imperfection to remind people of their powers. Could something similar be happening here?

Why is there a photo of an ancient Khmer temple in Cambodia at the top of this story?

The Spanish said they were there when they arrived. Appears the Spanish annihilated them. WHO directed the Spanish? Called JESUITS. Where did the wealth of these Peoples go, throughout S. America and the New World? ...Jesuits.

Many factions of the Jesuits are in fact satanist.

The spaniards brought deadly illnesses the indians had not developed any resistance against, like smallpox.

The Lycurgus Cup.
A strange chalice made its way into the British Museum’s collection in the 1950s. It is a 1,600-year-old jade green Roman artifact called the Lycurgus Cup. The image on the chalice is an iconic scene with King Lycurgus of Thrace...

Ancient Places

The highly-decorated tomb is built in a distinctive ‘L’ shape
A mysterious ancient tomb with “unusual and rare” wall paintings has been discovered in Egypt. Antiquities Minister Khaled al-Enany told BBC reporters the discovery of a 4,400-year-old tomb found during excavation work in Giza’s western cemetery “likely belonged to Hetpet, a priestess to Hathor, the goddess of fertility, who assisted women in childbirth.”

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
