Could there be a lost city, older than the towering pyramids of Egypt, lying quietly beneath the turquoise waters off the Cuban coast? For over two decades, curious formations deep under the waves have piqued the interest, skepticism, and unbridled imagination of scientists and adventurers alike. Is this the new Atlantis, or just Mother Nature flexing her geological muscles?
A Submerged Mystery at 650 Meters
West of Cuba, near the Guanahacabibes peninsula, mysterious structures rest in the eternal twilight 650 meters down. They were discovered more than twenty years ago, and their very existence continues to challenge long-held scientific certainties. Depending on who you ask, these could be the remnants of a sunken Caribbean city dating back 6,000 years—easily giving the Pyramids at Giza a run for their money—or they could simply be a geological curiosity expertly carved by nature itself. One thing is for sure: nobody’s throwing away their science books just yet.
The 2001 Sonar Surprise
The story really began in 2001, when a survey mission by Canadian company Advanced Digital Communications set out to map the Cuban continental shelf with sonar. Instead of the usual monotony, the sensors came alive with an unusual signal. There, in the chilly depths, appeared regular geometric shapes, lined up in neat, orthogonal rows. One team member confessed to the BBC that the layout “was reminiscent of streets and blocks.” Urban planning, Cuban underwater style? Maybe. To make things even more intriguing, images taken by a remotely operated vehicle revealed broad, smooth blocks—a bit like oversized masonry—resting squarely on the seabed.

History or Geology? The Dating Dilemma
Initial theories, approached with a healthy dose of caution, suggested an age of about 6,000 years for the structures. That would make them about 1,500 years older than the pyramids at Giza. If that dating were accurate, it would mean prehistoric Caribbean populations were building monumentally before anyone thought possible. But the story takes a twist: geologist Manuel Iturralde, from Cuba’s Museum of Natural History, noted in National Geographic that the depth of the site would point to a much older age—on the order of 50,000 years. That’s way before the appearance of any known complex human constructions, prehistoric or otherwise. So, unless we have an undiscovered civilization in our collective blind spot, things aren’t adding up nicely.
Could nature have played architect? Absolutely, says Iturralde. He reminds us that “nature is capable of producing structures that seem carved,” citing the slow, powerful forces of erosion, fracturing, and sedimentation. Truth is, with no physical samples or detailed 3D surveys in hand, experts can’t yet perform the deep petrographic or morphological analyses needed to solve the riddle of whether we’re dealing with clever humans or a masterful planet.
Suspense, Speculation, and the Long Wait
Since the last major expedition back in 2005, nobody has revised the script. The site remains shrouded in mystery, an ideal playground for speculation and enthusiastic discussions tying the so-called “blocks” to the legend of Atlantis. Only coordinated efforts involving oceanographers, submarine archaeologists, geologists, and sonar imaging experts will one day shed definitive light on these enigmatic undersea forms. Until then, the scientific world watches—and waits. For those who enjoy a good tale and a better mystery, perhaps patience is the greatest virtue of all.
In the end, whether what lies beneath the waves is the Caribbean’s answer to the lost city of Atlantis or just a geological quirk with an excellent sense of symmetry, only time—and some deep-diving scientific detective work—will tell.
