Local residents have mixed feeling about these mysterious rings. Some have suggested a particularly simple explanation. According to some local residents, these “giant” rings belong to the Austro-Hungarian empire put in place to help the transport of timber across the harsh mountains of the region.
Those who support this theory point out that these giant rings were somehow placed inside the mountains at a time when the Pannonian Sea still existed. These giant rings were used to bind ships, and the region was used as a sea port.
Local residents have stated that there are numerous other findings in the area which cannot be explained, and all of these findings are being deliberately hidden from the people.
These giant rings, and giant rocks that seem to be finely carved are found at the hills around Vogosca between Breza and Vares, near Dubrovnik and in several places in eastern Bosnia. There are also four of these at Bjelasnica and Vlasic, Vranica, Prenj, Velez, then Majevica, Bukovica near Travnik, above Stolac.
Dejan pelvis, a professor of history at the Prijedor Gymnasium believes that these rings of Kozara are one of those incredible mysteries associated to the past. All these mysteries share one and same fact – that no one can accurately explain their origin and purpose. These findings are shrouded in mystery.
