Ride a bicycle in the tunnels of an abandoned mine. 15 photos.

Hello my friends.
Today we will go on an underground journey through the abandoned shaft galleries. Millions of years ago there was a sea here. And all the sedimentary rocks of the limestone osev formed a stone. Half a century ago, stone blocks and sand were produced here.
The entrance to the mine with a beautiful graphite.

We are inside, me and my brother. Here is the realm of darkness and silence. And only occasionally fly bats.

Ahead are many kilometers of tunnels with different branches.

Sometimes there are places of collapses. There can be dangerous.

Someone was here. And spent a lot of time.

We move further into the depths of dark tunnels. In some places there is a difference in altitude.

A typical place for young people in such places ...

The temperature here is constant in both winter and summer. It is about 10-12 degrees Celsius. In the summer it's cold here, but in winter when it's freezing outside in the street.

Once in such places mushrooms were grown. But it was a long time ago...

Some places from the ceiling drip water, because the top of the earth.

This place is called "Eyes". Here, too, someone was lyking to gather and hang out.

We return back to the exit. Ahead of us is a stream of warm air - the exit is not far.

And the last look at the graffiti of an unknown artist ...
The journey is over, it's time to go home.

Thanks for watching and your attention.
