The four halls of the museum contain more than two thousand exhibits. The exposition begins with the display of documents connected with the beginning of the intelligence and counter intelligence activities in the Russian State. The following serves a good example: in 1380 thanks to Boyarin Zachary Tyutchev, who was the head of the embassy of the great Moscow Prince Dmitry in golden Horde, the Mamai hordes were smashed. Tyutchev misinformed Mamai about the Russian forces, and also obtained valuable information of the place and time Mamai was to meet Lithuanian Prince Oleg, who were supposed to make arrangements for uniting their troops.
