Not so long ago, I wrote an article about underground passages, but since there is a lot of information and much can be added, I decided to write another one with a more detailed description of all these underground structures.
As I said in the previous article about the tunnels, there are a lot of them, you can find them in almost any of the major countries, and Russia is no exception.
As for Russia, it is known about unexplored many kilometers of tunnels in Altai, and also, I wrote about the moves near Murmansk. Similar tunnels can be found under most of Europe, America, Japan and the Caucasus.
It is believed that the tunnels are a kind of "web" through which you can reach anywhere, from a certain point in the world. All due to the fact that some of the passages pass under the seas and cities, connecting countries.
Moreover, most of the tunnels have been processed along the walls and vaults, which already raises questions. Most likely, such work, on such a scale, cannot be done even with modern technologies, since the tunnels are really amazing.
In my previous article on tunnels, I wrote that you can get into them from almost any, even unexpected place, there is news that even in old houses entrances to strange dungeons were found.

However, some archaeologists and researchers say that the main entrances are the so-called "wells". Some of them have been found hundreds of meters deep, sometimes more than a kilometer.
Moreover, such inputs are also processed to a smooth state of the walls, but why did this need to be done? - We do not have an answer, and who did it and when is no less difficult question.
But not all tunnels are round. For example, in India, at a depth of almost 200 meters, a rectangular tunnel was discovered. And there are strange lines on the walls, similar to machining.
This very news about a tunnel under India appeared from Petronio Jaramillo, in the XX century. He said that when descending 200 meters, at certain intervals there were something like platforms, from which other multiple passages were already leaving. Generally speaking, something similar to a modern elevator and floors.
I don't really believe in the underground civilization that exists now, but it's easier to believe that this was done by the highly developed civilization of the past.
It is obvious that dungeons, especially at great depths, are safe in all plans, from wars to cataclysms. That is, if then technology allowed to do this, then an unknown civilization could create moves for a kind of refuge.
And also, do not exclude the fast travel version. Even if a highly developed civilization existed and it had flying vehicles, it is not a fact that underground movement is not simpler and faster.
In fact, we know nothing about the age and creators of these intricate and many kilometers underground tunnels, in principle, as well as about their purpose.
