Ten years of scientific and archaeological investigation of the Bosnian pyramids have brought many exciting moments as well as dramatic turnovers which are seeking the redefining of our knowledge about history. One such breakthrough happened in April 2015. During the six-months of cleaning and passing through new sections of the prehistoric underground tunnels, which had been discovered some time ago, the employees of the Bosnian Pyramid of the Sun Foundation were faced with various difficulties. During the winter of 2014 and spring of 2015, they hardly won new meters of tunnel. In one moment, in February 2015, one branch of the tunnel which leads to the South, toward the Bosnian pyramid of Sun, ended with a huge rock.
We decided to go around the rock by using side passageways. Like many other tunnels which we already discovered, these were packed with fill-out material (gravel and sand). Two side passages, to the East and West, ended in conglomerate material after about ten meters. We tried one more direction but that one didn’t led us to the desired result as well.
We went back to the entrance. We agreed to visit a section in the opposite direction. I said to Jock to go first and to record while the water is clear. Behind him were Anela and Meira, then Osman, Edo and me. We moved to the East. After a few meters we came to the first intersection. It has led exactly in the direction of the South. I liked that because it is the direction of the Pyramid of Sun. The tunnel, which was open, ran for about three meters before being filled with gravel material to the ceiling. We were stopped there and took a photo.
In front of us was a continuation of the tunnel in the direction of the Northeast. The water level was deeper in this section, approximately 1 meter. Osman returned back, and we continued. After seventeen meters we came to a new crossroads. Our route was blocked by stone walls and then filled with material. An open section continued to the left, towards the East. The water was becoming deeper, and found its way into my boots.
