Ancient Cities and Megalithic Sites Underwater

A wealth of human history lies submerged in ancient cities at the bottoms of lakes, seas and oceans of the world.

Some of these urban centers were sent into the water via earthquakes, tsunamis or other disasters thousands of years ago.

Many ruins have just recently been rediscovered, by accident or through emergent technological innovations. Some have even caused scientists to question the history of human civilization.

Unlike the fabled cities of Atlantis and Lemuria, the underwater ruins of the ancient Greek city of Helike were rediscovered in 2001. Buried underneath the remnants of a primordial lagoon, it is no longer a tantalizing mystery for writers, historians and enterprising explorers. A multitude of ancient cities and buildings have been found underneath the waters of our oceans. In the past couple of years, discovery claims surfaced of ancient underwater sites the size of Pompeii. As convincing as these claims are, no real proof has ever been found for the supposed Japan, Cambay and Cuba anomalies and these sites remain highly controversial. The following ruins serve as a reminder of Mother Nature’s might and of our glorious archaeological ancestry.

Seahenge Norfolk, England

Seahenge, also known as Holme 1, consisted of a ring of fifty-five oak trunks that formed a circular enclosure with a large inverted oak stump in the centre. The trunks were placed in a trench and not in individual holes with their bark facing outwards and split sides facing inwards. Placed about 3 ft into the ground, we will never know how tall the trunks actually were. It was built around the 21st century BC. After its discovery in 1998, the site was excavated despite protests from Neo-pagan groups and the timbers were cleaned and placed in permanent storage. A recreated Seahenge was placed at the original site and a museum opened to the public in 2008.

Sunken ruins of Cleopatra’s palace, Alexandria, Egypt

Off the shores of Alexandria, the city of Alexander the Great, lie what are believed to be the ruins of the royal quarters of Cleopatra. It is believed that earthquakes over 1,500 years ago were responsible for casting this into the sea, along with artifacts, statues and other parts of Cleopatra’s palace. The city of Alexandria even plans to offer underwater tours of this wonder.


Lost more than 1600 ago, Cleopatra’s palace as well as the temple of Isis was discovered in the archaeological waters of Alexandria. Legend holds that Cleopatra and Marc Anthony committed suicide to avoid capture by the Romans, who in turn destroyed and dispersed their belongings. Up to date, archaeologists have found three areas where they believe their tomb to be. More than 140 artifacts have been excavated so far, and excavation work continues to this day at the submerged royal quarters. Archaeologists are also researching the possibility of an underwater museum at the site.



Herakleion and Canopus, Abu Qir Bay, Egypt

Herakleion and Canopus were the twin cities guarding the gateway to Egypt. Herakleion was also home to Menelaus, king of Sparta, during his famous 10-year war against Troy. More than 1200 years ago, the cities abruptly collapsed when a flood turned the ground on which they were built into silt. Until their discovery in 1999, the only proof of their existence came from the texts of a few venerable historians and Greek mythology. The ancient ruins were discovered at depths of 20 – 23 feet (7 m), frozen in time, with its many temples, statues and other dwellings still demonstrating its former glory.


Baiae,Bay of Naples, Italy

Baiae was the home port of the Western Imperial fleet of Rome. Playground of the filthy rich and infamous for its corruption and decadence the site has delivered numerous Roman sculptures. As a stockpile of casts were discovered, some believe a workshop probably mass-produced copies of original bronze sculptures for the Roman market. Baiae was annihilated by Muslim invaders in the 8th century AD and completely abandoned by 1500. Due to the volcanic activity of the area, the structure ultimately collapsed into the ocean.

Pavlopetri Peloponnese, Greece

Pavlopetri is unique as it is the earliest submerged archaeological city to have been discovered. It had a layout of streets, courtyards, tombs and various buildings that has largely remained as it was millennia ago. Accurately mapped for the first time in 2009, archaeologists were amazed to discover the site sprawled more then 30,000 square meters. The town was engulfed around 1000 BC by an earthquake. A protected underwater cultural heritage site as listed by UNESCO, it remains in danger of being damaged by thieves, tourists and boat anchors.
The complex mix of expert archaeology, underwater robotics and state of the art graphics allowed the team to piece together the secrets of Pavlopetri, producing spectacular results.

Atlit-Yam Haifa, Israel

Dating from around 7000 BC, this is one of the oldest and largest submerged human dwellings ever discovered. In fact, for 9000 years the granular ocean floor preserved the site so well, that bugs can still be found in the grain stores and the skeletons are still lying peacefully in their graves. The ruins were discovered in 1984 and immediately gave rise to different theories as to how the well-developed ancient village met its ultimate demise. From a tsunami to the gradual rise of the ocean due to the systematic melting of the glaciers, the events leading to its ultimate fate will forever be shrouded in mystery.

Port Royal, Kingston Harbor, Jamaica

Home to prostitutes and pirates, Port Royal used to be the “Wickedest City on Earth”. Founded in 1518, it was a notorious port city and popular abode for English and Dutch privateers until their governments cancelled their commissions to confiscate Spain’s ships. As the privateers became pirates, the port became the hotspot for pirates from as far away as Madagascar. Destroyed and sunk in part after an earthquake in 1692, excavations have yielded historical documents, various buildings, thoroughfares and actual preserved food. Various plans are in the pipeline to redevelop the town into a main tourist destination.

The Shore Temple Mahabalipuram, India

The famous Mahabalipuram temple has always been encased in folklore. The legends spoke of seven temples that were so dazzling; the gods grew envious and sent a flood that submerged all but one of them, leaving the Shore Temple companionless. After the Tsunami of December 2004, a collapsed temple as well as several other structures and primordial rock sculptures used in the same era to decorate walls and religious shrines were exposed. It revived theories that Mahabalipuram formed part of the Seven Pagodas the first Europeans wrote about.

Bay of Cambay, India

A few years back discovered the remains of a vast 9,500 year old city. This submerged ruin has intact architecture and human remains. More significantly, this find predates all finds in the area by over 5,000 years, forcing historians to reevaluate their understanding of the history of civilazation in the region. The find has been termed Dwarka, or the ‘Golden City,’ after an ancient city-in-the sea said to belong to the Hindu god Krishna.


Bimini Road

The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near North Bimini island in the Bahamas. The Road consists of a 0.8 km (0.50 mi)-long northeast-southwest linear feature composed of roughly rectangular to subrectangular limestone blocks.

Although it is generally considered to be a naturally occurring geological feature, as a result of the unusual arrangement and shape of the stones some believe that the formation is the remains of an ancient road, wall, or some other deliberately constructed feature. For example articles published in Argosy (an American pulp magazine) and either authored or coauthored by Robert F. Marx, a professional diver and visitor to the Bimini Road, argued that the Bimini Road is an artificial structure.

Yonaguni-Jima, Japan

A mysterious undersea structure off the coast of Japan causes controversy – is this a natural geological phenomena or a man-made structure which changes the history books as we know them?

In 1986, a diver near the island of Yonaguni Jima, off the southern tip of Japan (around Okinawa) came across some strange structures about 25 metres below sea level. They appeared to be stepped structures with terraces and ramps. One of the largest pyramid structures is 600 feet wide and 90 feet high –with five separate levels of stone blocks with what appears to be road surrounding the structure.

These structures seem to have been carved right out of bedrock in a teraforming process using tools previously thought unavailable to ancient cultures of the region.



MEGALITHIC RUINS near Yucatan Channel, Cuba

A team of scientists continues to explore megalithic ruins found in the Yucatan Channel near Cuba. They have found evidence of an extensive urban environment stretching for miles along the ocean shore. Some believe that the civilization that inhabited these predates all known ancient American cultures. So far, only computer models of this mysterious underwater city exist.

Samabaj Lake Atitlán, Guatemala

Discovered in 1996, researchers have concluded that the ruins were originally an island until volcanic activity or a landslide sunk it 1700 years ago.
The buildings were drowned before the era of Mayan rule and artifacts discovered have left the impression that the area was abandoned in a hurry. Several ceremonial monuments have been uncovered as well as altars, incense burners, ceramics and other artifacts. Excavations are extremely demanding as the visibility is close to none and everything is covered with a very thick layer of silt.

Sunken Realms: A Survey of
Underwater Ruins from Around the World


Australian researcher Karen Mutton has compiled the world’s most extensive list of sunken cities and megalithic underwater sites currently known around the world. She begins by discussing some of the causes for sunken ruins: super-floods; volcanoes; earthquakes at the end of the last flood; plate tectonics and other theories. She then discusses Plato’s Atlantis and the various areas of the Mediterranean and Atlantic that have been proposed as the location. From there she launches into a worldwide cataloging of underwater ruins by region. She begins with the many underwater cities in the Mediterranean, and then moves into northern Europe and the North Atlantic. She continues with chapters on the Caribbean and then moves through the extensive sites in the Pacific Ocean and Indian Ocean. The final chapters are on ruins and structures in lakes and inland seas plus a brief look at modern and medieval sunken ruins. Comes with plenty of maps, illustrations and rare photos. Places covered in this book include:

Tartessos; Cadiz; Morocco; Alexandria; The Bay of Naples; Libya; Phoenician and Egyptian sites; Roman era sites; Yarmuta, Lebanon; Cyprus; Malta; Thule & Hyperborea; Celtic Realms Lyonesse, Ys, and Hy Brasil; Carnac, Brittany; Isle of Wight; Canaries and Azores; Bahamas; Cuba; Bermuda; Mexico; Peru; Micronesia; California; Japan; Indian Ocean; Sri Lanka Land Bridge; India; Sumer; and inland lakes in Scotland, Russia, Iran, China, Lake Titicaca, Wisconsin, Florida and more. A unique and fascinating book!

Being that mankind, especially in ancient times, liked to live along the coasts, it is not odd that this is where we find countless lost cities. This should be a warning to those who live on coasts now: You are at high risk for catrastrophic flooding caused by earthquakes, impact events, etc.

    It is very simple since there had to be a Pre Ancient Civilization ( or more) who stand here for thousands of year. Many old cultures spread over the globe are still telling same stories, share many linguistic patterns and share many culturistic issues. History of mankind is wrong, history has to be rewritten. The scientist who still says Yonaguni has a natural cause, is afraid.. Because ONLY Yonaguni is enough to rewrite history of mankind. And there are dozens of examples all over our planet. We call the cultural stories as myths and legends of great man, guess what after Thousand of years of plundering, destruction and reclaiming, those real stories became myths.. Mankind after the global reset, destroyed almost anything. Yonaguni, Baälbek, Eastern Island structures, Puma Punku, re-used Egyptian structures, and the list goed on and on… Those things survived the era before our own timeline.. Also many sites with still radioactivity.. Don’t be a biased scientist.. Jut open your eyes and use common sense.

  2. says

    Spot on with this write-up, I actually think
    this website needs far more attention. I’ll probably be back again to read through more, thanks for
    the advice!

    • says

      In the following link to photos and calculations regarding Yonaguni and nearby geoglyphs I note many errors.

      1. The WWII attack on the Aleutians was a fake out or feint to draw the attention of Admiral Nimitz away from the invasion of Midway and what would have followed. You can see this in the movie with Glenn Ford taking over aircraft carrier ops from Robert Mitchum as Halsey.

      2. The statement about a land corridor being closed across the Bering Strait is as bad as the Clovis theories almost. In the Riis-Wurm Ice Age era of 60,000 years ago the land bridge was there. I have also shown evidence of the Baidarka from Scientific American which demonstrates advanced boat designs including ivory bearings for weight distribution and catamaran hulls which were around in some form with outriggers going back over 150,000 years ago. Botany shows the Caroline Islanders travelled 1500 miles to bring flora and fana to Hawaii that long ago. Genetics shows 70,000 years of continual human habitation on Vancouver Island and many other proofs under many headings here at W-M. Guidon’s work ties in with Leakey at Barstow, Hueyatlaco is a little older and then you can argue about Acambaro. Check out Topper and even Dillehay – nope this is just alien theory nonsense! Yonaguni was part of the mainland for sure – and many other things are factual but the gist of it is not.

      3. John Anthony West and the other people weighing in on this are a blight upon truth in league with the Bible Narrative Annunaki crap. The truth is these rocks are man made just like the ones off Cuba from around the same time. I also think the Ainu were in Peru before this and DNA proves they are throughout Polynesia as well. Kennewick Man is Ainu according to Chatters and others from far more reliable scientific backgrounds. They should be treated as frauds like Zahi Hawass who has been shown for the money grubbing jerk he was.

      4. They should spell altar correctly or admit they are alters themselves. The idea that earth needed re-populating after the Ice Age is nonsense! People moved and did so for many Ice Ages and interstitiary or subdivisions known as Dryads. The need to re-populate after the Carolina Bays event of this era is real, but facts don’t fit their agenda. Drugs are the source of insights being used by Hancock today. His shamans of the Amazon would help him understand how attunement lead to a lot of knowledge he does not grasp including what is covered in the next point.

      5. They say: “The above photo shows a notch carved out of the hill right above the Yonaguni Structure. Could this have been a stairway leading down to the ceremonial location, or a harbor for a boat that would ferry people to the monument? Obviously this raises many interesting questions, not the least of which is; How did a 10,000 year old civilization know so much about the human reproductive process and what was the purpose of the ceremony.”

      I say how can people be so dense as to think it was not well known and maybe even more fully understood (leading to genetic cross-breeds now being proven). Churchward shows many urban sites like Pohnpei tie in with Tiahuanaco in the time before and during the eras they speak about.

      6. They say: “Of course, there are years of scientific study, in many scientific fields, that this information opens up. It is not the intention of the Faram Foundation to circumvent any established scientific protocols, but to offer food for thought and discussion in an expeditious manner outside the normal, and often tedious, academic arena. All our work is copyrighted. However, anyone is free to develop our ideas past the stages that are offered in our articles in hope that some type of recognition will be given to the originators of the information. Even the information that we offer on our websites is available for broadcast in the media provided proper recognition is given as to where the information originated.”

      I say: They get in the way of real research and make a mockery of those who try to explain things with facts. By promoting Alien Theories as Hawass/Cayce allowed you get a majority of humanity thinking all such discourse is useless or a fraud.

    So having watched Charles Marcello’s link on Advanced Building materials, my question is why are we being lied to? Just because people of recent history had some building knowledge that we don’t today? What’s the big deal? You mean the ego of the science community is that fragile that we can’t be told that we don’t know how they put these statues together? Really?

  4. Brenda Brown says

    I think searching for underwater sites is absolutely necessary if we’re going to discover the truth about what was, and what happened. With all the reports of volcanoes, comets or large fragments slamming into the earth etc., there should be multiple places that ended up beneath the waves. And even though people have written a lot about Bimini, with all the activity around it and other like sites, I don’t know how we can’t be getting in there and doing some decent research to find out what’s really going on. I once read Charles Berlitz’s account of clandestine groups finding and grabbing artifacts from some of these sites, before anyone got wind of it, so the more people make their searches public and open, the more the truth will come out.

    • Brenda Brown says

      Thank you Charles Marcello, for the link above. I appreciate having it to look into whenever I can grab a minute or two.

    The man’s inner urge to trace his origin takes him to the very depths of seas where he finds nothing but one mystery veiling the other, thus intensifying the the curiosity thirst more than ever. Still astonishing work …..

  6. Underwater Science Fiction says

    this are some amazing findings, the have uncover in the ocean. I agree with the others are saying, there may be many more stuff to discover.

    New knowledge about water /static electricity/

    Movement of static charge between materials takes place spontaneously, in all cases, the charges equalize or the material with the greater charge gives charge to the less charged material. This sometimes occurs as an immediate discharge and sometimes it’s very slow, but in all cases this goes on until the settlement of the value of their energy potentials. The human body and basically every living substance has charge. Each cell is from a physical point of view also a bearer of electric charge. Therefore, in some cases the energy in our bodies goes away spontaneously, in other cases, it is obtained spontaneously. How this happens during various different circumstances is mentioned at

    It follows that we live in an environment where this little known factor – the static charge – can be harmful in excess, while in other cases, it may be beneficial to our health. The electrons from the external world can subtly manipulate the processes going on in our body. In case of an absence or on the other hand an excess it may interfere with body immunity, and may also cause health complications.

    Current medicine does nothing to address the value of the charge of our body. It actually does not deal with the amount of charge on our cells, of which our body is composed. Doctors remove only the consequences of a possible overvoltage or under-charge of the ideal amount of our physical charge; the causes of the disease whose nature is often in the outer harmful energy effects, are not dealt with.

    Medicine, as a discipline, is not the only science that does not deal with the negative effects of static electricity on the cell membranes of humans. In other fields, such as architecture, the environment, chemistry, physics and other fields, the static charge changes the properties of the matter.

    It is remarkable that the ancient cultures already knew about the effect of static charge on human health. Archeologists have shown that hundreds of thousands of pieces often made of a hundred ton massive rock, were deployed across the country. Occasionally someone would move a small rock for a short distance by the use of towing ropes and announces that rocks of great weight were transported in the same way. This however does not sound plausible. Scientists have dealt with this issue in the course of history without success and the colossal work of our ancestors ended up in mysteries.

    If we would like to solve that megalithic “Gordian knot”, we first need to postpone the widely known “textbook knowledge” and go back to prehistoric times and responsibly look at the mystery of megaliths, which may hide some help in the same way as monastic libraries do. It can not be overlooked that the sacred buildings of all kinds were located in the vicinity of watercourses, the zones of natural sources of static electricity. The matter of these structures accumulates static charge, which is then spontaneously transformed into organisms of worshipping believers. This process was magnified by burning candles. This used to be used centuries ago but the laws of physics haven’t changed since. This energy transformation process in the bodies of visitors is identical in the church buildings of stone masonry of all kinds at present as well. Energy gain is perceived as pleasant feeling. Conversely, a close contact with a person that is energetically weak can feel uncomfortable. The friction between two objects with different dielectric constant creates a static charge and this is a physical fact that has been known for centuries. In the last century, the fact that water flows generate static electricity was, perhaps intentionally, neglected. Sacral structures accumulate static charge in their mass – energy that is produced by mutual friction of two diverse non-conductive or poorly conductive materials – running water, shorelines and bottom of the watercourse. The first material are the water molecules, the second material is a rock through which the water flows.
    If we can not understand everything on earth without justification and put it rather off into the realm of miracles, see e.g. water, rock, Lourdes, it would be broadly beneficial, if we focus more intensely on the research of the often neglected natural force – static charge (electricity), and its properties that are still unknown.

    Only GREAT convulsions of the earth could cause a city to sink 2,200 feet below sea level. The same kind of convulsions that could lift oceans up to cover continents described in the hundreds of ancient accounts of the great flood.
    Hint: Venus was Nibiru, and it destroyed two planets as it came in; Mars irreparably, and Earth mostly until it slowly revived. This is why the earliest written accounts of Venus describe it as having a long cometary tail that stretched accross the heavens. This apparently died down by the mid-B.C. era.

    This is the sort of quality article and quasi educational resource, the internet needs more of and horses for courses sport, mere economics and drivel, cascaded to their own channels across all networks. Every time a serious and profound matter like this occurs, we get interference or some un-related topic thrust before us – the ‘every 5 minute’ audience-change phenomena. Thankfully, this excellent article shows some can see a more sustained thematic of wide-spread interest and encouragement. Not so much the questation as ends or means for wealth in themselves, but depth of appreciation and value to the fit of what we may know, to better inform and validate claims, myths and dismissals, and keep things under review. I hope the Ark at Ararat and the link with Noah’s sons and significance will also be included in such theatres. It underscores the need for more objective learning, than contractual, risk averse and warped bents ‘industrialised’ learning ‘blinkered’. Thanks.

    I believe we need to search out those of us who are of a like mind to develop major foundations that do nothing but fund and discover the lost treasures of our past. Preferably we would have one organization of funding purposes that solicits funds from those who have a little wherewithal to participate and help develop programs. Virtual Reality would play a very important role so those of us on the land could swim through these new finds for a price. I believe this site could serve as a catalyst to such an organization.

    Wonderful ! I have believed for many years that ancient civilizations have lived on this earth for millions of years. These pictures of the structures of recent peoples confirm my thoughts and think those people who discover them are doing a marvelous job .
