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

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.
