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 12,000 years ago. 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.
In the book Secrets Of The Underground Door To An Ancient World (German title: Tore zur Unterwelt) German archaeologist Dr Heinrich Kush states that evidence of huge underground tunnels has been found under dozens of Neolithic settlements all over the European continent. These tremendous tunnels are often referred to as ancient highways.
