Tunnels to the Sun: Exploring the Mysterious Ravne Tunnels in Bosnia

In 2005, Dr. Semir Osmanagich discovered the Bosnian pyramids in the heart of Bosnia and Herzegovina, in a small town called Visoko. He found five pyramids which he called the Bosnian Pyramid of the Sun, Moon, Dragon, Love, and the Temple of Mother Earth.
In addition, he found a tunnel, called Ravne, which is 2.5 kilometers (1.55 miles) from the Bosnian Sun pyramid. When the Ravne tunnel network was first discovered, people called it a cave as it looked like a hole in a hill. However, this would later become one of the most mysterious tunnels in the world.
