Evelyn Hart – Indian Defence Review Oct 16, 2025
In the summer of 2001, a Canadian research team conducting routine sonar mapping off the western coast of Cuba spotted something unexpected. Beneath 2,000 feet of Caribbean water, their equipment returned images of symmetrical stone structures—linear formations, circular patterns, and pyramid-like shapes sprawled across the seafloor. To the untrained eye, they resembled an ancient city plan, the kind etched into textbooks or imagined in myths.
What followed was a flurry of speculation, headlines, and high hopes. Could these be the remains of a long-lost civilization, predating even Egypt’s pyramids? Or was it simply geology playing tricks again—an illusion conjured by time, tide, and tectonics?
More than two decades later, the site remains unexplored in any serious, peer-reviewed capacity. The original expedition led by Advanced Digital Communications (ADC), a Havana-based company working jointly with the Cuban government, collected initial footage and sonar data. But funding dried up. Institutional interest waned. And the site, located off the Guanahacabibes Peninsula, slipped back into the quiet of the deep.
Yet as old images resurface on social media and fringe theories re-emerge in digital documentaries, so does public interest. In a scientific landscape defined by data, the mystery off Cuba’s coast endures not for what we know—but precisely for what we don’t.
Sonar Echoes and a City-Shaped Illusion
The 2001 expedition used side-scan sonar, a common method for mapping the seafloor, typically employed to locate shipwrecks. What they found instead were formations stretching over several square kilometers, laid out in rectilinear grids. Initial footage from a remotely operated vehicle (ROV) revealed what looked like massive blocks with smooth surfaces and sharp edges—some rising in shapes reminiscent of step pyramids.
Paulina Zelitsky, a Russian-born engineer and co-founder of ADC, told BBC News at the time: “It’s a really wonderful structure which really looks like it could have been a large urban center.” But she also urged caution: “It would be totally irresponsible to say what it was before we have evidence.”
Despite public excitement, peer-reviewed archaeology journals have never published formal findings on the site. No academic institution has verified the sonar images or ROV footage. Without physical samples, there’s no material proof—just ghostly echoes on a monitor and the tantalizing possibility of misinterpretation.
Too Deep, Too Old?
One of the biggest challenges to the lost-city theory is depth. The structures lie roughly 650 meters (2,133 feet) below sea level. For a human-made settlement to be submerged at such depths, it would have to be at least 50,000 years old, according to Dr. Manuel Iturralde, former chief geologist at Cuba’s Natural History Museum. That predates any known civilization by tens of thousands of years.
“Sea level hasn’t risen enough in the last 6,000 years to submerge something that deep,” Iturralde told National Geographic in a 2002 interview. He reviewed the ADC data and called the formations “peculiar,” though he admitted geological explanations—like fractured limestone platforms or coral terraces—could not be ruled out.
Still, natural formations of such apparent symmetry are rare. And that ambiguity continues to invite both professional scrutiny and amateur fascination.
Why No One Has Returned
Despite the bold implications, no major scientific institution has returned to the site. The University of Southampton’s School of Ocean and Earth Science, one of the world’s top marine geology research centers, has never publicly addressed the Cuban discovery. Neither has NOAA nor UNESCO’s underwater heritage program.
In part, that may stem from the difficulty of deep-sea exploration. A return expedition would require advanced ROVs, geological sampling tools, and a multi-disciplinary team. Costs would likely run into the millions—an investment few are willing to make without clearer evidence.
And then there’s the political context. The discovery occurred in Cuban territorial waters during a period of tight U.S.–Cuba tensions. Collaborative research has always been complicated, even more so for a privately owned Canadian-Cuban venture operating under a media spotlight.
The Myth That Won’t Sink
While scientists tread carefully, the internet doesn’t. YouTube channels like Ancient Architects and independent coverage by ArkeoNews have revived the story, drawing links to Atlantis, pre-diluvian civilizations, and pseudoscientific timelines. The site has become part of a growing constellation of fringe narratives—where geology blurs with mythology and sonar maps become Rorschach tests.
Still, genuine experts remain intrigued. Zelitsky, now retired from deep-sea work, once described the structures as “too organized to be natural.” But without follow-up data, such claims hang in limbo.
In the end, the only certainty may be the ocean’s ability to hide its past. Whether the Cuban anomaly is a case of misread geology or a sunken chapter of prehistory, the mystery underscores a simple truth: more than 80% of the ocean remains unmapped and unexplored.
Interesting!
What’s on the images certainly *looks* human-made.
Wow, older than Atlantis!
Cuba should offer deep-sea tourism to view these fantastic remains….One shouldn’t just leave these topics up to Graham Hancock.
Didn’t Edgar Cayce prophesy that some such remains as these would be discovered off the coast of Cuba?
Very simply, this is part of Atlantis which sank approximately 12,000 years ago. An important part of our planet’s suppressed history.

Kudos for TTS posting articles of this nature. I recall berating RS for not touching this subject a while back.
Whether these photos are genuine remains to be seen. Should they be forgeries they do not invalidate the idea of older civilisations. The scale of the structure likewise seems lacking. Do they measure in inches or feet? It may well be of the order of 50,000 years old.
Tel Aviv Mike has disparaged “Atlantis”. It is one of the memes he bundles together with others to discredit by association with whomever he arguing against – the debating technique of a knave.
Indeed “Atlantis” can be used artfully to disparage its context. Atlantis was a specific place referred to by Plato, and I believe Plato. I have seen sources that suggest it may have been a city reached via the Northern African coast by now absent waterways. The so called “Pillars of Hercules” not being the Gibraltar Strait as is sometimes suggested…
Never mind. “Atlantis”, can be used as a loose placeholder for generic pre-flood civilisation that in no way designates it as THE “Atlantis”. I also caveat “pre-flood” by saying there have been numerous changes in sea level over the ages and I am not restricting myself to the Biblical/Gilgamesh flood.

A shout out to HP WRT to the Cremo book that I noticed he commented upon on another article. I like Cremo and reviewed his book. By far not as good as his presentations. I do wonder whether the dating he uses is correct. It maybe that dating techniques – based on current notions of change – are incorrect. This potential error comes from reactions other than chemical – that is nuclear – taking place in decaying organic materials. Notwithstanding the greater age of mankind than current mainstream discourse allows for IMO.
This is a big subject and while I read a lot on this last year it is not at the forefront of my mind at the moment. It touches upon the Structured Atom Model that leads into discussions of nuclear transmutation. (I arrived here via the Electrical Universe paradigm..)
Theoreticians have suggested the neutron is merely a proton-electron pair that gives rise to atomic packing aligned with the Platonic solids – yes, Plato again! But I’m sure this will all be Greek to many folk…
The book is “The Nature of The Atom: An Introduction to the Structured Atom Model”
2,100 feet? That’s deep! The rule is, anything that is straight & linear in the ocean is not natural. Seems like it would attract major attention, but no. So what does that tell us? If they found & explored the Titanic, why not this? Where is the National Geographic funding? Or funding from any number of organizations? Is it alien? Something doesn’t make sense.
At 2,100 feet, it’s dark down there. Not blue. So I guess the images are enhanced to bring out the sonar images? We’ll probably never hear about it again. It never mentions WHEN it was discovered, only a reference to a 2002 interview. That’s odd. Why is this the first we’ve ever heard about it? Things don’t add up with this story.
Could be some of what was left in the time of the Great Flood in the days of Noah, 4,000 years ago.
I know! Let’s put all these things together and build an intersellar “spaceship” so we can escape the prison planet called “earth”. What with batteries under the pyramids and lost atlantis’s coming out our rear ends, it’ll be easy. All we need to do is capture one of icke’s lizard men to tell us all the secrets and the flat earth will be ours…
I’m a bit suspicious of these images. I do believe mankind is far older than we’re being told and maybe an ancient neolithic culture could have worked stone to these great engineering standards, but with no clue about the scale of these images they do look small to me, more like like a model. I know they’re supposedly assembled from sonar images but does sound underwater cast shadows like that?
There appears to be no erosion from salt water, tidal movements, coral buld-up or depositions in the water dissolving the stone etc. And after 50,000 years underwater they shouldn’t look so pristine and sharp-edged, especially when the seas were rising the tides breaking over them for hundreds of years before they were finally submerged should have done immense damage to all those edges.
It may be from people who find structures on the moon or Mars etc.
History runs in very long cycles. There have been countless high tech civilisations that have peaked then been destroyed by natural (or human) catastrophes.
One day ours will go the same way. Such is life!
These structures are obviously manmade. It is irrelevant how deep they are. These ruins were once on dry land probably during the last ice age when Oceans were much lower in depth. These ruins are deliberately being ignored by standard archeology because they don’t fit standard text, like so many out of place and time structures around the world.
The reason Mike the kike doesn’t like it could be because it is much older than his precious hashem. Tough luck, Mikey.
“On the same day that Krishna departed from the earth the powerful dark-bodied Kali [demon] Age descended. The oceans rose and submerged the whole of Dwaraka.“
– Vishnu Purana – volume 2, p. 785
But there’s no such thing as Dwarka because if there was they’d have some epic splainin’ to do. Ohhhh riiiiight, they did find it, start to map it and recover artifacts until “funding ran out.” Aw shucks, the most telling discovery in history, Krishna’s city, one which would compel research into other aspects and events of the Mahabharata and no darn money to do it. Imagine that..
The Underwater Ruins of Dwarka
Fed up with this idea that knowledge because it is power is the privilege of the few who generally share nothing unless we put a gun to their heads. Moon landings, 9/11, debt-rigging, global warming, Covid, real science, what is in the vaccines, fake elections, fake science, you name it – the truth is considered the exclusive privilege of the Controllers, and to make matters worse all of the insiders in their top-down command, in their arrogance and elitism firmly believe and act as if they have an absolute right to lie to us about anything they want. NO FACTS = NO FREE WILL = NO FREEDOM = NO PERSONAL RESPONSIBILITY = NO JUSTICE = NO TRUST = SLAVERY = REVOLUTION.
“The wreck of the Titanic lies at a depth of about 12,500 feet (3,800 meters) in the North Atlantic Ocean.”
“The deepest dive by a diver in a submersible was performed by Victor Vescovo, who reached a depth of 10,928 meters (35,853 feet) in the Challenger Deep of the Mariana Trench on April 28, 2019. This was the deepest point on Earth and a record-breaking dive for a manned submersible. ”
This is only 2,000 feet down. If there is any manmade structure down there WE HUMANS OUTGHT TO KNOW EVERTHING ABOUT IT. THE CONTROLLERS HAVE TO WAKE UP. NO MORE BULLSHIT OR THEY DIE!!!!
Simon Smith, this might be of interest as well.
Maybe even entertaining.

Cool. The pyramids are much older than they are alleged to be. And the Bosnian pyramids are even older, apparently 30.000 years or so.
Humans are laughable. Anything shoved in front of them that fits their ideas is instantly believed. Why is the “sea floor” all around the “structures” perfectly flat? Why is the background texture (the “sea floor”) so regular? Why is the foreground blur (the dark bits) so regular? Why do some of the “structures” change shape and even disappear depending which “image” they’re in? Why didn’t the “scientist” go right up to the “structures” to get a closer look? And more than anything, why does it look like a child’s CS project? You’re all off in fantasies of “atlantis” from a kid’s doodles. I would imagine that the reason no one has “gone back” is because actual scientists can spot a fake a mile away.
If that was real (LOL) then there’d be other buildings between it and the shore, not just there but all over the world. Are there? No. Why? Because it’s click bait. They didn’t just build those buildings and have nothing else on their land did they? All the other buildings, that would’ve been further inland, would also be there, under the water, between those buildings and the shore.
Then there’s the 650 metres of water. If that were true, the whatever-they-weres would’ve have to have built those buildings at sea level – i.e. on the beach. Would you? No. You’d build them on much higher ground, so you’re talking way more than 650 metres of water. Do you know how much water that is? Taken from the top of all the oceans of the world. Exactly where was that water at the time? LOFL.
Then there’s the super ridiculous people saying it was atlantis and it “sunk” into the ocean. Get yourself a bowl of flour and build sandcastles in the middle. Then nudge the edge of the bowl. What happens to your sandcastles? That’s what would happen to anything on an island that sunk into the ocean, which, at the end of the day, would be the top of a mountain, with the mountain collapsing under it. It wouldn’t leave the buildings standing neatly in a row. They’d turn to dust.
It’s all true I tell you!
LOFFFFFFL.
on Google Earth I saw ca 10 – 20 km wide spoors
strict to thousand miles long on PACIFIC seaground .
how come they into this Google Earth ? AI ? what for ?
and I cannot believe that a satelite camera can see the
seaground thousand meter deep .
Ocean levels went up 300 feet at the end of the last glaciation, here is the chart:

Most large towns are built at sea level where a river meets the sea. Whatever existed when the ocean levels were low disappeared. Amensia of previous culture happened just as it does now – if I wanted to know what my home town was like 100 years ago, I would have a hard time finding out.
In ten thousand years from now, Portland, Oregon of 2025 will be high an dry.
Read a book called Cyclic Deluges by William Walker Bassett. It explains how this happened.
