Introduction

So much can be written about pyramids. We now have evidence that the biggest pyramids were constructed more than 12,000 years ago (Atlantic Period). They are situated on a world grid with the prime meridian going through the Cheops Pyramid in Egypt, and they are encoded with a different (than ours) mathematics (see Carl Munck code). We find hidden chambers and tunnels underneath them, and they are present on every continent.
The biggest pyramids on Earth were constructed in the Atlantic Period, Smaller pyramids were built at later dates when the knowledge of building them had been lost. Usually people think there are only pyramids in Egypt, and Middle America. However every continent has them, although sometimes they are not recognized by the scientific establishment. China has hundreds of them, some of very tall. For a long time they kept it a secret, and even today they don't talk that much about them. Tall pyramids, totally overgrown, recently have been discovered in Indonesia, as well as one large one in West Java!
The pyramids in Bosnia were discovered in 2005, in the town of Visoko, also totally overgrown. They have so much dirt and vegetation on them, that they must be very old. It is an important discovery because not only are they comparable with those in Egypt in size, but it also implies that once there was a thriving, very advanced civilization in Central Europe about which we know nothing. It is also important because the scientific community originally denied they are pyramids, but now most of them remain silent because the evidence of artificial construction keeps growing. The excavations and studies are being done by lay people and a few scientists who were willing to lose their reputation and embrace the possibility of new discoveries never dreamed of. Because it is in the hands of people who have open minds, discoveries are being made and will be made, without the heavy censoring of the orthodox scientific community, without the hiding and destroying of evidence that does not fit their theories. For example, it has come to light that Egyptologists know all the underground tunnels, cave, tombs and rooms in the Giza plateau, which they have been exploring and robbing in secret, while officially claiming they don't exist. The Bosnian pyramids are important because it has become clear from in the beginning that the tunnels around and underneath the pyramids had been carefully closed and filled up with debris. At some time in the past someone had taken a lot of time and effort to seal everything off. That means that whatever lies down there, or inside the pyramids is still intact! Although I think they didn't leave behind anything truly important, such as their advanced technology.
A New Archeology has taken birth. Archeology is no longer exclusively in the hands of narrow minded scientists who only acknowledge evidence that supports their preconceived ideas about human history. Any evidence of advanced civilizations been systematically rejected by archeologists. They also view the past of humanity as primitive and uncultured. With the discovery of the Bosnian pyramids, all this is going to change. We finding very clear evidence of a technologically advanced society more than ten thousand years ago, being uncovered and investigated by a growing number of scientists with open minds, along with some ordinary people who bring many new and unconventional ideas, like pyramid energy. The discoveries are just starting, and it will be very interesting to see what develops..
What you will find here is just a synopsis of the discoveries.

5 to 10 ton stone blocks are found on all sides of the Pyramid of the Sun. The entire pyramid is covered by these blocks (as far as has been uncovered), and they were man-made, a sort of concrete, molded into shape.

“What is most interesting is that samples were sent to the University of Paris where a world-leading materials professor tested the properties of the concrete. It is as much as five times stronger than any concrete we can make today and five times more resistant to water as well."

Beneath the Bosnian Valley of the Pyramids there is an extensive underground tunnel and chamber network which runs for a total of more than ten miles, connecting all pyramids and other places together. From in the very beginning (on discovery of an entrance) it was found that all side tunnels were closed of by stone walls and filled up with river bed material. It took a lot of time and work to remove some of them and take the fill material out. Following a tunnel that lead to the Pyramid of the Sun, they stumbled upon two open tunnels with water in it. They also had side tunnels that were walled of. One led to the Pyramid of the Sun. The entire tunnel was clear, with stone walls at the sides, and fresh water upstream. As the ceiling dropped, they continued to explore with a flat boat until the height was too small. It looks like this was a channel from a water well which starts under the pyramid. See below for pictures.

One of the problems with underground tunnels is air flow. The architects of the Bosnian tunnels solved this problem by varying the height of the ceiling. Air circulation in the tunnels is perfect and it allows normal breathing all the way. It was made possible by different ceiling heights that caused different air pressure pushing the air as a natural fan. Slope is at the 1,5 degree which is the same slope we use today for the fine water drainage. Negative ions concentration is dozens of time higher than average. It would make atmosphere clean of bacteria and viruses which would explain benefits to the human bodies inside this complex. 

A big breakthrough happened at the Second International Scientific Conference on Bosnian Pyramids held in September 2011 in Visoko, Bosnia-Herzegovina, where Klaus Dona presented a map of the underground tunnel system present in the Pyramid of the Sun. The map came from a a friend of his who works with sophisticated ground penetrating radar from satellites. It shows several levels (depth) of tunnels, probably connected to each other by vertical shafts, and couple of chambers. Klaus Dona said that most of the chambers are empty, but one "contains bones, and something else that will surprise you when you find it".

The tunnels are color coded: light blue is 5 meters ( 15 feet) under the surface, white is 10 meters (30 feet) deep, blue is 40 meters ( 120 feet) deep, brown is 70 meters (210 feet) deep, yellow is 150 meters (450 feet) deep, black is 180 meters (540 feet) deep, red is 350 meters (1050 feet) deep. The circles are rooms or hollow spaces.
Independent researcher and executive director of Serbian Research center “Duh Rtnja” Saša Nađfeji has further analyzed Klaus Dona’s map:

Other Ancient Stone Constructions in the Area

The Bosnian Pyramids by themselves show that they are the constructs of a very well developed society. It is only logical that such a society built more than just pyramids. Thus people have been looking around and, yes, they found other evidence.

1. Stone Spheres

Large stone spheres have been found in Costa Rica and Middle America, associated with ancient cultures who were able to shape perfect spheres out of different rock, some of them very large. Well, Bosnia has them too! To archeologist they are just an artwork, but those who work with energy know that they are placed (if still in original position) on earth energy spots, and thus have a function in energy transformation or distribution.

So far (2016), the biggest stone sphere found, in the town of Podubravlje in the middle of Bosnia. It has a radius between 1.2 and 1.5 meters (4 to 5 feet). Based on the brown and red color, it is assumed that is has a very high content of iron. if this is the case, then it must weight about 30 tons. It might be even bigger than the biggest stone sphere in Costa Rica.

Archaeological Park: Bosnian Pyramid of the Sun Foundation

I think this one is a natural concretion sphere, because of the iron content and the presence of layered shells, clearly visible in the picture. Nevertheless, it might have been hauled from another place and positioned here for the distribution of the local energy field. We now know that the very ancient cultures have not a problem with moving very heavy, multi-ton stones.

Bosnian of the Pyramid of the Sun Foundation has registered more than twenty sites in Bosnia and Herzegovina which have mysterious stone spheres, shaped and composed of various different materials: granite, volcanic rock and sandstone.

This sphere is located in the "Deep Creak", near Zavidovići-Central Bosnia. More than 40 stone spheres were found on this location, weighing many tons. They are very similar to the stone spheres found in Costa Rica, Mexico and Easter Island.

This big stone ball found in Bosnia (near the village of Slatina, Banjaluka).

A lot of spheres have been covered by dirt for thousands of years and are usually discovered by accident. The local population have sometimes moved them near their house.

There are two interesting articles about the Bosnian stone spheres at http://independent.academia.edu/NenadDjurdjevic

At Ginje, a village nearby the Bosnian pyramids, a tumulus (a hill shaped by man) was found, with large man-made stone blocks on top. The local villagers told that many of the stones of this hill were carried away for construction of buildings in their village.

3. The Cyclopean Walls of Daorson

Daorson was the capital of a Hellenised Illyrian tribe called the Daorsi. The Daorsi lived in the valley of the Neretva River between 300 BC and 50 BC. The remnants of Daorson can be found at Ošanići, near Stolac, in Bosnia and Herzegovina.
Archeologist tell us that some primitive tribes cut huge blocks of stones, right angled, surfaces flat and weighing tons, to construct their buildings, without considering they didn't have the tools to move or lift them. The stones have been cut so precisely that you cannot get a credit card in between.
These stone blocks, and their construction, are the same as in Middle America (f.e. at Ollantaytambo, Machu Picchu and Sacsayhuamán) and other places around the world. It doesn't take much to see that the walls at Daorson were already there when the Illyrian tribes moved in. These constructions, now shown to also be in Europe, were once built by an advanced worldwide civilization.
