Tunnels Linked Ancient Cultures
Is it possible that ancient cultures were interconnected thousands of years ago? According to thousands of underground tunnels that stretch from North Scotland towards the Mediterranean, the answer is a big yes. While the reason behind these sophisticated tunnels remains a mystery, many experts believe that this huge, 12,000-year-old network was built as a protection against predators and other dangers. Some experts believe that these mysterious tunnels were used as modern-day highways, allowing the transition of people and connecting them to distant places across Europe.
