Researchers are baffled by the number of Stone Age subterranean tunnels they have unearthed. They recently discovered enigmatic tunnels in Scotland that reach all the way to Turkey and date back 12,000 years.
These scientists feel puzzled regarding the reason and method the mysterious structures were built. The latter appear painstakingly made and magnificent, and these attributes make them even more perplexing for the experts.

Some researchers claimed that the uncovered tunnels were for people’s protection against predators, while others pertained to the structures as ancient roads.
Henrich Kusch is the author of the book, “Secrets of the Underground Door to an Ancient World.” He pointed out that the massive subterranean tunnels had been excavated literally under hundreds of Neolithic communities across Europe.
In an archaeological site in the Saudi Arabian desert, researchers have found 12,000-year-old tunnels with a gigantic ancient underground network.
The findings were made at the site of Shishan (or Shiswan) Cave near Turaif, Saudi Arabia by research team from Griffith University and the King Abdulaziz City for Science and Technology in Saudi Arabia.
The tunnels are tens of meters long. The width ranges from 1 to 2 meters and height from 4 to 6 meters. There are also drawings on the cave walls of a number of animals such as cows, ibexes, birds, and goats. The drawings give some idea about what was around them during that time period according to CBS News
The researchers found in the article were investigating a geological feature called salt domes. These are large underground tunnels that form when layers of rock containing salt are pushed up to the surface. The researcher who studied the area, Virginie Krakowicki, said that she suspected that there may be something more to these formations.
In a statement, she said “We wanted to know if it was possible for man-made structures to exist or if these were part of natural geology” and then went on to say “We can now confirm our hypothesis about the existence of man-made structures”
The 12,000-year-old underground tunnels were found by a team of researchers led by Dr. Richard Taylor and Dr. Alastair Keyes at the Stonehenge World Heritage Site. The “Stonehenge Hidden Landscapes Project” used sophisticated geophysical imaging technology to scan the surroundings inside and outside of the monument.
The findings revealed that there are long tunnels and caverns that extend for miles underneath Stonehenge and many other prehistoric sites in the area. Some of these tunnels go as deep as 30 feet underground and were built around 5,000 BC, which is 6,000 years before Stonehenge was erected from around 3,000 to 2,500 BC.
The reality that these peculiar structures have lasted for nearly 12,000 years shows that the original ones were much larger.

Furthermore, Kusch believes the underground tunnels were intended to function as roads and let people journey to far-flung areas throughout Europe from the Mediterranean to the north in Scotland.
The writer described them as interlaced with nooks, with some being larger and with seats or rooms and storage chambers.
Kusch pointed out that the massive underground tunnels form a gigantic covert network when combined, even though they do not all link or connect.
Moreover, he claimed that his group had found 350-meter tunnel networks in Styria, Austria and 700-meter underground tube networks in Bavaria, Germany.
Kusch said that most of these vast underground structures are not much more massive than giant wormholes but are merely 70 centimeters wide. This fact makes them broad enough for people to squeeze through, yet not much more.

Additionally, the writer noted in his tome “Secrets of the Underground Door to an Ancient World” that churches were often constructed around tunnel openings.
He explained that it was because these religious institutions were typically afraid of the pagan heritage that the underground tunnels could have symbolized, and they hoped to counteract their effects.
Besides the European continent, similar underground tunnels have been unearthed on several other continents. A number of these ancient structures were discovered in the Americas.
Scholars continue to determine and provide definitive explanations on why the weird underground tunnels were erected in the first place and how they were put together.
