The Exceptional Underwater City of Cuba: A New Theory on its Origins – Part I


(Read Part II here )

In his Underworld: The Mysterious Origins of Civilization , Graham Hancock examines the numerous structures that have been discovered underwater around the world. Most of the sites that Hancock discusses lie less than 120 meters (395 feet) below sea level, which comes as no surprise since the sea level never fell below this mark during the time Homo sapiens walked the earth. Submerged over 700 meters (2300 feet) underwater, the Cuban city discovered by Paulina Zelitsky and Paul Weinzweig during a joint Cuban-Canadian expedition is the singular exception.

Overturning Old Theories

How can the existence of this underwater city at this great depth be reconciled with the well-established consensus that the sea level never dropped so low? In Hancock’s own words: “What one would not expect to find in water anywhere near as deep as 700 meters would be a sunken city - unless it had been submerged by some colossal tectonic event rather than by rising sea levels.”

However, the hypothesis that the city was originally built at a higher altitude and subsequently sunk to its present depth through tectonic activity has not stood up to the scrutiny of the experts. Grenville Draper of Florida International University considers it highly unlikely that such an event could have occurred: “Nothing of this magnitude has been reported, even from the Mediterranean…”

Supposing Draper’s remarks rejecting the likelihood of the city having submerged are reliable, we are compelled to accept that the city was built at more or less the same depth that the city is located now. In other words, we are faced with the patently absurd conclusion that the structures were built underwater! Though proponents of the aquatic ape theory may beg to differ, it is clear that we have reached an impasse. Could there be an alternative theory that satisfactorily accounts for these structures at such depths?

Great Seas and Vast Depths

On the opposite site of the Atlantic Ocean from the Caribbean Sea is the Mediterranean Sea. Dividing Europe and Africa, the Mediterranean Sea is an enormous sea - over 2,500,000 km2 (965,255 square miles) that has, at least within the timeline of anatomically modern man, always existed. For millennia, ships of successive great nations and empires sailed the Mediterranean; the Phoenicians, Greeks, Carthaginians, and Romans among them. In 146 BC, owing to its victories in the Punic Wars against Carthage, Rome achieved what no known civilization had hitherto achieved; namely, the control of the entire Mediterranean Sea by a single power.

The Romans, rightly so, called the sea that they ruled over  mare nostrum –  “our sea”. Could the Romans have ever imagined that “their” sea, long before the dawn of man, was once a dry and landlocked basin? Indeed, they may very well have. In Natural History, Pliny mentions in passing a tradition of the inhabitants near the Straits of Gibraltar: “they also believe that [The Straits of Gibraltar] were dug through by him; upon which the sea, which was before excluded, gained admission, and so changed the face of nature.”

Could it be that the Caribbean Sea has a similar geological history as the Mediterranean Sea? That is, could the Caribbean Sea have been a dry basin, and could it have been so during the existence of anatomically modern man? Having performed an exhaustive search on the topic, I couldn't find a single source within the alternative literature let alone a peer-reviewed scientific paper that put forth such a hypothesis. However implausible this hypothesis may be, if true, it would provide a simple and elegant solution to the problem discussed, namely that of how a city could have been built close to 700 meters (2300 feet) below sea level today, or 580 meters (1900 feet) below sea level even during the maximum drawdown of the world's oceans. If the Caribbean Sea simply did not exist for an extended period of time in the human past, a reasonably advanced civilization inhabiting the area could have built cities on dry land thousands of feet below sea level, even over ten thousand feet below sea level.

When the Caribbean Sea was formed, these cities would have been submerged to a depth equivalent to the depth below sea level that they were originally constructed. The Cuban underwater city would merely be one of these hypothetical cities; thus, an explanation has been provided for the existence of the city at such great depth without recourse to either the city having collapsed to its depth or it having been built underwater.

The Land and the Sea

What are the necessary conditions for the Caribbean Basin to have been dry?

First, the West Indies archipelago, instead of being a string of islands (lying above sea level) separated by numerous waterways (lying below sea level), as it is now, would have had to be a strip of land lying above sea level throughout its entire length. In other words, the Yucatan Peninsula must have been connected to Cuba via a land bridge, instead of being separated by a strait, and Cuba with Haiti, and Haiti with Puerto Rico, and so on, until finally, the island of Grenada must have been connected to the South American mainland with a land bridge, instead of being separated from it by a strait.

Indeed, if the West Indies were like the Central American isthmus as it is today, unbroken and uniformly above sea level, the Caribbean Basin would have effectively become what geologists refer to as an endorheic basin, a basin that is isolated from the world ocean. However, the isolation of the Caribbean Basin from the larger world ocean, though necessary, is not in and of itself, sufficient for it to have been dry.

In order for the Caribbean to have been dry, there is another necessary condition that must have been met; namely, there must have been an excess of evaporation over precipitation over the basin's watershed. Today, there is indeed an excess of evaporation over precipitation over the Caribbean region, but was this true throughout the entire time behaviorally modern humans have existed, which has witnessed a great variety of climatic conditions? Most likely, the answer is yes, as the tropical and subtropical regions, to which the Caribbean region belongs, have undergone minimal climatic variations even amid the tumult of the ice ages and interglacials that have taken place over the Pleistocene epoch. Therefore, it is reasonable to infer that the Caribbean region had a water balance of evaporation in excess of precipitation throughout much, if not all of the human past, just as it does today.

Taken together, these two conditions, both of which are necessary for the Caribbean Basin to have been dry, are sufficient for this to have been so. That is, if the Caribbean Basin were both isolated from the Atlantic Ocean  and evaporation exceeded precipitation over its watershed, it must have been dry.

Given that the latter condition has already been established as highly likely throughout the time period in which man existed, demonstrating that that the former condition also held, shall suffice to prove that the Caribbean Basin must have been dry. Thus, we have established that the Caribbean Basin indeed could have been dry and hence habitable if the Caribbean Basin were isolated. This begs the question: Could the Caribbean Basin have been isolated? In other words, could the West Indies archipelago, which is now an island arc interspersed with deep and numerous waterways, have once been a contiguous landmass uniformly above sea level akin to the Central American isthmus?

For starters, the book is forbidden from God, and the religion is a cult. 

God warned us in Revelation 22:19 that any who add or take anthing from His Word will spend eternity in Hell. So Islam, Jehovah’s Witnesses, and Mormon all ignore that warning at their own peril. All those cults were started hundreds of years and more after God’s Book had been completed.


God created EVERYTING and NOTHING is impossible for God.

He got His book exactly as He wanted it to be, whether you believe there are books left out or not.

What a lame God He would be if He failed in getting His messages out unadulterated. 

To the author – thank you very uch for the excellent article, your hard work and dedication.


Revelation 22:19

“And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.”


Take care

The New perspective explains an understanding of the life-cycle of the planets, Kalpa. This basic process helps explain the Yuga phases, with time and size proportional to the movement of the planets. The basic process has been defined in the pre mentioned website ( ) in an article titled the movement of life. This is a scientific hypothesised theory explaining the movement and direction of the formation of the planets. Very basically like a whirlpool the rotation of the planets are drawn towards the sun. A planet is born on the distant perimeter of the solar system and progresses through many phases until finally cremated by the sun. This attraction is due to the burning of the sun resulting in a consuming, luring, drawing, lighter, thinner atmosphere closer to the sun acting as a suction. This helps explain the saurya manvantara concept. The planets grow through phases from fertilisation through freezing and gaseous phases, as seen by all the current positions of our planets, until a magical phase of flowing water. Water is evaporated too close too the sun and is frozen too far from the sun, but a phase of stability allows for the expression of life (confirmed by Nasa) as a planet passes through this zone of water. As a zone of expression it is also a database for the record of life. Inferior planets that have passed through this phase have recorded an historical memory, recorded within this phase of water. So as a new planet enters this zone, an accumulative record gives guidance and experience to the formation of life for the next planet.
This basic logical contemporary scientific understanding of the planetary movement has given a new comprehension of the biblical structure from genesis to revelations being an expression of the planetary life-cycle. Although imaginatively expressed the fire cremation is a logical cycle for the planetary movement. As all are aware if the Earth was at a slightly greater distance from the sun, then the temperature would be cooler and a cycle longer and so life would also have been larger with the contributing factors. Within the cycle of water a maximum volume of water is logical for Earths movement through this phase, it is described Earth is just passed this mid point also correlating to the flood or maximum point of water recorded in history.
The New Perspective is an extensive study of our Worlds animals and it is known now that distinguishing features of animals are directly linked to the anatomy of the World as seen in my picture. (click to enlarge) Upon the study of numerous species it is evident a single species also changes correlated to the World anatomy, if residing on the head of the World, distinctive head characteristics are expressed.
It is known now that our ancient civilisations plotted the World body anatomically directly linked to the picture posted on my profile here. The heads of Easter Island are where you can see the head of the World. The 12 zones of the body are recorded traditionally around the World. The lungs of Leo the sphinx. The womb of Virgo. This sunken city posts the neck of Taurus. Stonehenge is the sign of Cancer. World zodiacs contain pictures of animals and usually rotate opposite to Celestial zodiacs, like the Denderah zodiac.
The evolution of life on Earth adapts to this process of the planetary movement, although the energies related to Purusha or more constant creative cosmic energies express a basic structure made more complex the smaller it gets.

I want to thank Gord (didn't miss the r ) and Osiris for your intellectual thread related contributions. I am familiar with the modern concept of "the New Perspective" with regards to planetary formation and the concept of the phase of water, or phase of expression.   This is the zone where water is stable as a liquid, related to it's position in the solar system. Too close to the sun and water becomes evaporated and too far from the sun water is in a frozen state. The New Perspective describes the theory of the movement of the planets through this water zone. NASA and other astronomy research facilities search for other planets now within this zone or parameters, for the greatest probability of sustaining life. 
Water when gained by a planet through this movement would also have an absorption factor creating a long term expansive effect of the planet until the point of removal. As the accumulation of water increases so to does the compressive effect due to weight and the gravitational forces. Once a point is reached, of a maximum water level and changes to a phase of removal then additional and opposing forces react.

I agree, the reasons for the lack of follow-up on this is probably political. Too bad...I'd love to see some new imaging attempts, at least.

By the way, I thoroughly enjoyed this article as well. Your hypothesis is original and compelling, IMO.

Thanks for your comment! I'm glad you enjoyed the article.

I think the expanding earth theory is somewhat plausible. But shouldn't we be able to measure expansion if it is really happening? Do you know of any attempts to detect this expansion?

I think the discoverers of this underwater city just gave up trying to get funding for the follow-up expeditions and moved on with their lives...and since the city is in Cuban territorial waters, there's a lot of political red tape, especially if any Americans would be involved..
