Special Underground Fortified Area (15 pics)

Before the beginning of World War II it was decided to build the "the Zone total defense” around Moscow. It included a variety of fortifications which should have held the Nazis on the way to the borders of the capital for some time. Buildings, bunkers. tank guns and a lot of trenches were built at once. Prisoners should have held the boarder. The whole area was covered with charges just in case. Fortunately the defense was not required. The enemy army was stopped several kilometers before the area.
