Crimea, once located on the border of the USSR, was the territory where numerous top-secret objects were concentrated, which were not recommended to be spoken out loud. The book tells how they arose and what became of them now. Mysterious bunkers, antennas, dungeons and towers - in the Crimea you can find many abandoned military and scientific facilities. Here they forged the nuclear shield of the state, from here they controlled lunar rovers and spacecraft launched to Mars and Venus. This book proposes to follow the footsteps left in Crimea by the Soviet empire and open unknown pages of the history of the peninsula.
