Among them is Dr. Alexander Koltypin, a geologist and director of the Natural Science Research Center at Moscow’s International Independent University of Ecology and Politology.
Koltypin has analyzed ancient underground structures across the Mediterranean and identified similarities that lead him to believe the sites were once connected. Furthermore, the weathering of the structures, their material composition, and the geological features and historic changes in the region, lead him to believe they were built by an advanced civilization hundreds of thousands or millions of years ago.
“When we examined the constructions … none of us never for a moment had a doubt that they are much older than the ruins of the Canaanite, Philistine, Hebraic, Roman, Byzantine, and other cities and settlements that are placed on it and around,” he wrote on his website.
He climbed a hill about 1,300 feet high near the Hurvat Burgin ruins in Adullam Grove Nature Reserve, central Israel. As he looked over the site, he recalled a similar feeling from when he had climbed to the top of the rock city Cavusin in Turkey.
Erosion and Mountain-Formation
Not all parts of the purported complex are still underground. Some have come far above ground with geological shifts throughout history—the ancient rocky towns of Cappadocia in Turkey, for example, which Koltypin includes in the complex.
Some parts may also be found under the Mediterranean Sea, as is indicated by structures along the coast.
“According to my estimates, such depth of erosion … hardly could be formed in less time than 500,000 to 1 million years,” he wrote.
He hypothesizes that part of the complex was brought to the surface as a result of alpine orogeny (mountain-formation).
The composition of building materials at a site in Antalya, Turkey, which Koltypin calls the “Jernokleev site,” are also some 500,000 to 1 million years old by his estimate.
Archaeologists usually date the man-made structures at Jernokleev to the Middle Ages. But, Koltypin says the materials indicate a much older age.

What he identifies as a pink “cement” includes in it man-made ceramic fragments and basalts of volcanic origin among other materials. The last time an active volcano would have been present in the region to provide the basalts would have been some 500,000 to 1 million years ago.
As a result of the Earth’s crust moving over distant ages, parts of the underground complex have been plunged under sea level, Koltypin said.
Similar Megaliths and Underground Entrances.
The similar megalithic ruins at the various sites are part of what led Koltypin to surmise a connection between the sites, united in a giant prehistoric complex.
Megalithic blocks weighing tens of tons seem to have at some point likely been attached directly to the underground constructions, he said. “This circumstance gave me a reason to call the underground structures and geographically related ruins of cyclopean walls and buildings as a single underground-terrestrial megalithic complex.”
He noted that structures built on or near the sites by the Romans or other civilizations are comparatively primitive.
It is within a context of other findings suggesting advanced prehistoric civilizations that Koltypin puts forth his hypothesis.
