The three-storeyed communication bunker we’ll visit today has been abandoned since 2005. Its location is very difficult to determine as it is hidden deep in the Bialowieza forest.

Find a small hill in the forest and if you are attentive enough you will see some massive hatches on its surface.

That used to be the main entrance. There was a big building above it.

An inclined descent is followed by a massive door.

“System number 8”. What can it mean?

‘Put your shoes, soldier’s blouse, trousers and underwear into a rubber bag and don’t takeoff your respirator’.

‘Put your documents, money and topographic maps in a polyethylene bag’.

‘Process your hands, neck and bag with documents with special solution and take a hygienic shower’.

The lamps signal where one can go and where one must stay.

The ceiling in the part of the object is rusted. Soon the same will happen to the entire object.

Ventilation systems 1A and 1B.

Many rooms are empty.

That was not a regular room.

The floor was standing on powerful pneumatic springs to withstand a possible blast wave.

A huge conditioning unit KD-20.

Cut parts of system number 3.

The stairs lead to the ground floor.

‘Attention! The aggregates switch on remotely’.

Let us go down to the second floor. The place is filled with water but walking is still possible.

This is one of some rooms where people used to live.

1 meter separates the hall from the water.

In case of an accident the screen of the amperemeter is back-lightened.Its data could be seen in spite of darkness around.

Three generators form the heart of the bunker.

There used to be a stair that had been removed.
