“The Ravne Tunnels have been under continuous investigation and excavation since they were discovered by Dr. Sam Osmanagic, back in 2006. It has always been his assertion that the Ravne Tunnels are a prehistoric network of passages associated with the nearby Bosnian Pyramid of the Sun. Skeptics often dismiss the Ravne Tunnels discovery as nothing more than the remains of a medieval gold mine or a product of former Yugoslavian army activities. In this video, we once again provide scientifically derived evidence that proves the skeptics wrong (again) and supports Dr. Sams hypothesis. Earlier in 2020, the Bosnian Pyramid of the Sun Foundation sent two stalagmite samples for radiometric dating. The stalagmites were found stratigraphically above one of the Ravne 3 Tunnel Drywalls. This means the drywall must be older than the age derived from the stalagmites. The age of the stalagmites and therefore the minimum age of the drywalls has far reaching implications, beyond Ravne 3 and the Bosnian Valley of the Pyramids,” is stated in the press release by the Archeological Park: Bosnian Pyramid of the Sun Foundation.
