This is an interview with Dr.Stjepan Coric, a bosnian sedimentologist, working at the Austrian head office of geology in Vienna. I showed him a piece of the breccia stones from the excavations of the northern side of Visocica hill.
Dr.Coric can you analize this piece of stone from Visocica hill?
This is breccia as can be found on top of Visocica hill, formed in the Myocene appr.7 Mill.years ago when the Sarajevo-Zenica plain was filled with sweet water. The surrounding hills are non volcanic but sedimentary. The breccia is rather rough with larger pieces of crashed and also round stones pressed together with sand as cement. Some parts show erosion from water diffusing through the layers of soil and grass which are covering the breccia.
When have you been to Visoko and the Visocica hill?
I have studied and cartographed the area in March 2006 before excavations started and could not find major beccia quarries in the vicinity. This observation leads me to the conclusion that the breccia was built by nature in situ, which leads to the next conclusion that Visocica hill as a whole is consisting of breccia. Except the plateau on the west side, which is consisting of sandstone slabs and came down from the mountains by a nature cataclism.
But these sandstone slabs are rectangular with 90°edges?
Sandstone comes in every shape and size and therefore cannot be defined as man made just by its rectangular or square shape.
Also the breccia appears cut and is placed on top of the hill surface in a 45°angle?
Nature can lift or shift breccia plates in any degree. We need to be very careful with our expertise.
When will you be back to Visoko for further investigation?
I will be back by end of June
What exactly will you be investigating?
1.Where is the breccia stone quarry?
2.Is there statistically significant appearence of certain stone slab sizes?
3.What is the size and shape of the breccia stone layers found at the 5 sondages?
4.What is underneath the breccia plates?
5.Are the tunnels natural caves or abandoned mining tunnels?
Can you give us a statement whether this is a pyramid or not?
At this point there is just not enough evidence to make a clear statement for a serious geologist. We need more data, more excavations, more investigations.
I would be happy if I could say this is a pyramid, no doubt, but at this point it is too early.

The patterns within the rock shown at the top of this article are nothing more than natural Liesegang banding (rings). Natural Liesegang banding from the “Bosnian Pyramids site” (rings) can also be seen at:
As documented in numerous published papers, they are natural in origin. This is discussed in “Liesegang Banding (Rings) Confuse Another Archaeologist Again” at:
Brief discussions about tehir origin can be found in “Geologic Pattern Formation at http://wwwitp.physik.tu-berlin.de/~krug/geol_en.html
