Through the last few decades, scientists have discovered a number of mysterious ancient giant rings at numerous locations in the Bosnian mountains.
How is it that these stone rings were found along a shoreline of a 30 million year old sea? That is the question that has most scientists scratching their heads.

These relics are thought to date back to the era of the Pannonian Sea, said local inhabitants, and there are tales suggesting that their users are giants who roamed the lands millions of years ago.

Some locals believe that these “rings” were from the Austro-Hungarian empire, who set them up to facilitate the transport of timber across the harsh mountains of the region.

Although the Pannonian Sea disappeared around 600 000 years ago, it was not a short-lived sea. In fact, it lasted for about 10 million years. Although, the sources on this duration differ ― some claiming that the sea lasted for over 30 million years. The Pannonian sea existed during the Miocene and Pliocene eras.

If they are in fact from a sea port, then the time of their usage must have been well before the human race existed (approximately 240,000 or older). There was an ancient sea at least 10 million years old near the rings, begging the question: who or what built these rings?

Other than the fact the rings exist, there is little to go on and a lot of speculation online. Could these be evidence of some very advanced and old civilization? Could this be some other device for purposes unknown? All we have is questions and very few answers.

The rings were utilized to bind ships as the region acted as a seaport. There are also myths related to giants and their huge ships, who made those giant rings. However, could these rings actually date back millions of years? How were they made, and what material were they made of?

According to the local population, it is believed that these “artifacts” date back to the era of the Pannonian Sea, and legends suggest these were used by giant beings who inhabited the area in the distant past.

Recent discoveries point to a time when giants roamed the Earth. The mysterious giant rings that were found on top of mountains suggest that these were used by giant beings who inhabited the region millions of years ago.

There are legends in the region that speak of giants and their huge ships. There are assumptions that these giant rings were made by giants, ancient ship owners and sailors who inhabited the region in the distant past.

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. The locals stress how important it is to examine these findings.
The theory that these rings date back to millions of years is based on the fact that the Pannonian Sea, which disappeared around 600,000 years ago, existed in the area of the present-day Pannonian Plain roughly 30 million years ago.

Should these ships be unable to reach the ports, there would not be any good reason to create such giant rings to bind those ships. However, there are a number of people who know how the rings look like claim that they weren’t used to tie the boats to the coast.

Humans did not appear during the period that the Pannonian Sea still existed, leading to experts questioning the identity of the boat builders. And if there would be no humans to create boats at that time, who would have possibly made the rings.

In fact, the first hominis able to build tools date back to roughly 200,000 ago, and the time gap between them and the disappearance of the Pannonian Sea is 400,000 years.
Kozara, where the giant rings were found, was an island in the Paratethyan ocean 50,000 years ago. As the Pannonian Sea withdrew, the coastlines appeared. This is why, Dragan Romčević, director of the National Park “Kozara” states that these giant rings cannot be from this period.

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.

This is a topic on which scientists cannot offer explanations to, simply because it lacks logical facts, and since science cannot explain these mysterious artifacts, people have no choice but to interpret the phenomena themselves, and then, everything becomes possible.
