Before the beginning of the WWII an edict to create a "zone of total defence" around Moscow was adopted. This area included different fortifications that could detain fascists for some time if they came up to Moscow. Huge buildings, bunkers, tank guns and trenches were constructed very quickly. That is prisoners who must hold the defence. Fortunately there was no need to do this. The enemy army was stopped on the approaches to the fortified area. Here we'll speak about one of such places that is located in Nakhabino town of the Moscow region.
