Bunker!

There is a real bunker not so far from the memorial. It is excellent placed on a terrain and you never find it without able guide (is the wrinkle clear?) It's walls has 1.2 meter weight, floor - 0.8 meter, good concrete with armour, anti blast wave defence of entrance to the bunker (so called "skwoznik"), airing system, underground barracks, electric generator, and so on and so far. You could see the deep trench leads to the entrance to the bunker.
