The sunken city in Cuba located at an unimaginable depth of 700m is truly a difficult problem for scientists in decoding this phenomenon.
In 2001, the marine engineering couple Pauline Zalitzki and Paul Weinzweig discovered the ruins of an ancient city covering 2 km² at a depth of 700m off the coast of Cuba.
With permission from the Cuban government, they used sonar equipment to scan the area and found stone structures resembling an ancient city.
In July 2001, geologist Manuel Iturralde joined in and determined that this could be an ancient citadel.
Huge stone structures, smoothly hewn and stacked in circles and pyramids were discovered.
The city lies at an incredible depth of 700m, making it difficult to explain why it sank so far.
There are some theories that the city was submerged by rising sea levels about 50,000 years ago or sank into the water, possibly where a land bridge between Guanahacabibes and Yucatan once existed.
The Taino people, the indigenous people of Cuba, have a legend about the sea, telling of a great flood that submerged the land, creating the sea.
In addition to the construction and subsidence theories, there is also the possibility that the sunken city is a natural artifact, not a human construct.
