Tunnels to the Sun: Exploring the Mysterious Ravne Tunnels in Bosnia

(Read the article on one page)

In 2005, Dr. Semir Osmanagich discovered the Bosnian pyramids in the heart of Bosnia and Herzegovina, in a small town called Visoko. He found five pyramids which he called the Bosnian Pyramid of the Sun, Moon, Dragon, Love, and the Temple of Mother Earth.

In addition, he found a tunnel, called Ravne, which is 2.5 kilometers (1.55 miles) from the Bosnian Sun pyramid. When the Ravne tunnel network was first discovered, people called it a cave as it looked like a hole in a hill. However, this would later become one of the most mysterious tunnels in the world.

Materials in the Ravne Tunnels

When the Ravne tunnels were first discovered, one could only enter for some meters. The tunnel was filled with a loose material which had a brownish color and was very soft. This is called the “filling material.” The walls of the tunnels were made of conglomerate and it seemed like someone dug through this conglomerate many years ago. The conglomerate has a different color and texture than the filling material.

Many that are against the Bosnian pyramid project claim that the foundation Archaeological Park: Bosnian Pyramid of the Sun, is making these tunnels themselves. However, this is not true, as one can clearly see by studying the different materials. If the foundation was digging the tunnels, then only one material would be found - and that material would be the conglomerate. However, the foundation is following the filling material and excavating it. There are two different materials in the Ravne tunnels.

Two of the main tunnels. The filling material is in the middle, while the walls, which are the conglomerate, are on the sides.

Not only that, but there are also dry walls in the tunnels which block the different side tunnels halfway. Almost every place that there is dry wall there is also a side tunnel with filling material which only leaves some centimeters of empty space at the top. There are several side tunnels with different dry walls that are found in the underground site. In summary, there is evidence that some cultures or civilizations were involved in the creation of the Ravne tunnels - they are not naturally made.

A Gold Mine of the Middle Ages?

There are many hypotheses regarding the Ravne tunnels and its purpose. Several people argue that the tunnels were mines and probably from the Middle Ages. The most common hypothesis is that these were gold mines.

This hypothesis can be easily proven wrong; one just has to study the different materials discovered in the tunnels. To this day, no gold, silver, glass etc. have been found in Ravne. In fact, the Ravne tunnels have almost no materials that were important in the Middle Ages.

Some people also state that these were more modern mines. However, in more recent times, people were mining for coal, and again, there is no coal to be found in Ravne. The materials that are found in Ravne are often conglomerate, sandstone, clay, quartz crystal etc.

People in the Middle Ages did not use their time and efforts to mine for these materials. Furthermore, if this was a gold mine from the Middle Ages, there would have been some historical records about it, but none have been found. Plus, gold would probably have been found in Ravne at some point during excavations, but to this day no gold has been located in the tunnels.

A Mysterious Oil Lamp

In 2012, volunteers made a discovery in one of the tunnel sections in Ravne. It appeared to be an oil lamp from the 17th century. The oil lamp was on top of the filling material and on one side of the tunnel.

This shows that someone entered the Ravne tunnels not so long ago. In my opinion, those who entered the tunnels did not enter from the entrance that was discovered by Dr. Osmanagich in 2006 because that entrance had some halfway closed tunnels. One may say than that the Ravne tunnels have multiple entrances which are connected to each other. One of these tunnels, which could be a new entrance, is the Ravne 2 tunnel, which was discovered in 2015.


How about these being tunnels nade by an animal ? – could there have been large rodent type animals in this area way back...these look more like giant rabbit tunnels than anything else ! Of course they are big, but so were the aniumals many aeons ago !

The tunnels are named ‘’Rabbit Hole,’’ but they have no connections with rabbits. It does not make any sense that an animal would make so complex tunnels, escpecially not tunnels with side tunnels, dry walls, six tunnels that are going to the same direction etc. These tunnels are shaped by man. It still needs a lot of research if we are going to figure out who was involved in these tunnels. 

This is so cool. I keep thinking everything that can be discovered has already been done. Looks like there's plenty more to be found.

These remind me of the 200-250 km long tunnel network built by the viet Cong in Vietnam during the French and later American invasions.

And certainly some smaller ones here are air vents.

It may have got blocked by some ancient flooding which may have had silt or mud mixed in the waters.

I wouldn't dismiss the small ones as off limits to humans. In Maharashtra state of India you have ellora caves. These have small tunnels drilled (or something) into rock. Cameras on Remote controlled vehicle have found carvings on the walls. These spaces are too small for normal adults to enter.

Maybe kids were sent in. Though I doubt kids can carve realistic stuff on its walls. In any case why?

Outside there are various idols and figures of stone. At the base of each are small human figures. The assumption is that these small statues at the feet of larger ones are lesser gods or vanquished enemies. What if there were a race of small sized humans?

That mountain is not showing as a built pyramid, and we know pyramids are founded on flat surfaces which is not the case here. this story is likely inaccurate.

All you know is what you are told, so don't pretend your nonsense/gibberish actually means something.

The Lycurgus Cup.
A strange chalice made its way into the British Museum’s collection in the 1950s. It is a 1,600-year-old jade green Roman artifact called the Lycurgus Cup. The image on the chalice is an iconic scene with King Lycurgus of Thrace...

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
