Civil Defense Bunker in the Forest Near Lachema, Řečkovice

The surface cover with two inlets (so it has no emergency exit) is in close proximity to the factory. Access to it was provided through a special gate. In the surrounding terrain, the floor plan of the cover in the shape of a square is clearly visible, so it is not an extensive hide.
Near the first entrance are suction tubes equipped with damping baskets. It is not possible to decide whether both belong to the filter ventilation device or to one for the diesel generator, which would take care of the power supply in the event of its failure. Their close proximity suggests more for the second variant.
The second second entrance is much narrower, the door is double-leafed again. To the left of the door, there is a bell button on the counter-pressure wall if someone arrives late during combat operations, after closing the shelter.
