Built, Not Dug: KTK Tunnel Was Left as an Empty Space in an Artificially Constructed Claystone Hill in the Bosnian Pyramid Complex

by Jock Doubleday

On May 14, 2015, a KTK Visoko employee named Muhamed kindly offered to show me an ancient tunnel, the entrance to which is on the edge of the property.  

KTK Visoko is a leather processing plant that was closed for 20 years during the Rothschild/U.N./Serbian war against the Bosnian people. A company called Prevent purchased the clothing plant in June 2014, but the factory continues to have a largely abandoned look.

Muhamed and I walked across the empty factory grounds toward the Bosna River, a large river that meets the Fojnica River nearby. 
 

Approaching KTK

On the southwestern bank of the Bosna River, just below the tunnel entrance, an ancient artificial claystone block lay deeply embedded into the hill just above water level. The block was steeply inclined into the artificial claystone/clay hill. This was the first clue that the hill in which KTK Tunnel found itself was not a natural feature of the landscape but an ancient built structure.

Exploring KTK

On the southwestern bank of the Bosna River, two tunnel entrances can be found at a height above the river of approximately 10 meters. (Only the main tunnel entrance is depicted, because its cousin entrance about 15 meters to the left at the same level could not be accessed due to the steepness of the hill at that point.)

Note artificial clay layers 1) inclined into the hill to assure
structural strength and 2) inclined toward the tunnel itself.

Government-mandated support posts and beams. The clay pieces that have broken off over time collect on the flat wooden "roofs" and eventually collapse them, thus creating life-threatening danger for visitors. Without the government's interference, only one clay piece at a time would fall, a circumstance manageable with a simple hard-hat.

When Was KTK Tunnel Built, and Who Built It?
 
Clearly KTK tunnel was not built in modern or Roman times. 

Building a tunnel-containing hill -- out of anything, but in this case out of clay and claystone layers -- that rises 60 feet above a river has no precedent in modern or Roman construction. 

Further, there would be no reason for Romans or modern builders to build a tunnel with a ceiling height of between 10 and 15 feet.

With its extremely high ceiling, KTK Tunnel is an enigma. Why would human beings 5 to 6 feet tall build a tunnel twice their height? 

Of course, there is copious paleontological evidence that humans have walked the earth who were anywhere from 9 feet tall to more than 25 feet tall. So the tunnel could have been built for 9-to-10-footers. 

However, some of the passageways in Ravne Tunnel Labyrinth, which is part of the same pyramid complex that KTK Tunnel is, have ceiling heights of only 3-5 feet. 
 
Thus, perhaps the tunnels were built, not for negotiation, but for something else.


Why Was KTK Tunnel Built?

We are left with the question: "Why would an ancient civilization build a claystone hill with empty space in the form of a high-ceilinged tunnel?"

We can give a partial answer to that question.

The entrances to KTK are 30 feet above the height of the Bosna River in springtime. The ancient hill -- and the other, much larger, structures in the Bosnian Pyramid Complex -- were built on what had been a level plain. If the tunnel entrance had not been placed high up, water would have flooded it immediately. 

The ancients' solution to the problem of tunnel building, in this case, was to create their own hill, a hill that would protect the tunnel from flooding.

Of course, we still haven't answered the question of why they wanted to build a tunnel in the first place. Mysteries abound.

If you have any ideas on this subject, or if you have heard of or visited another tunnel that was built, not dug, please drop a line to the author.

Archaeological Park Foundation Explores Two Newly Discovered Water Channels in Ravne Tunnel Labyrinth

On April 30, 2015, a scientific team led by Dr. Semir Osmanagich, discoverer of the Bosnian Pyramid Complex, explored two newly discovered water channels in Ravne Tunnel Labyrinth, a tunnel system that winds beneath the ancient pyramid complex in Visoko, Bosnia.

These water channels were open when they were discovered as side tunnels t-ing off of the main tunnel passage being excavated. 


Most of Ravne Tunnel Labyrinth's passageways were closed (filled to the brim) an estimated 4,600 years ago with "fill-in material" -- loose sand and small river stones. When Foundation workers encounter filled-in passages (most of them), the passages are excavated with shovels and wheelbarrows. This work has been progressing since December 2006, four months after Dr. Osmanagic discovered the tunnel entrance 2.5 kilometers northwest of the Bosnian Pyramid of the Sun.

But these two water channels, and all water channels found to date in Ravne Tunnel, are fully open and need no excavation.

No one knows why the advanced culture who filled in this elaborate prehistoric tunnel system plugged approximately 90% of the tunnel's passageways but left the water channels completely open.

The two water channels explored for the first time on April 30, 2015 were found in early April at the "front" of the tunnel where work has been progressing throughout the winter. 

The water channels are approximately 500 winding meters from the entrance, and perhaps 35 meters beneath the surface.

The water in the channels is clear and in pristine condition. This has always been the case when water is found in channels or pools in Ravne Tunnel Labyrinth.



Satellite scans using ground-penetrating radar performed in 2011 and 2014 have shown that the labyrinth of winding tunnels that compose Ravne Tunnel meet with at least one tunnel that leads to another winding tunnel system beneath the Bosnian Pyramid of the Sun.

The entire tunnel system also connects to a tunnel beneath the Fojnica River to the Bosnian Pyramid of the Moon. 

The Foundation's excavation progress continues today. Donations to this excavation effort can be made here:
