Krasnokamenka was a closed city of Ukraine where in the Soviet times there were built underground shops to collect nuclear warheads there to be subsequently transported to launch sites all over the central USSR and some Warsaw Treaty countries. For almost half a century this place was being surrounded with myths
and legends but when Ukraine became an independent state the city was opened and all warheads were taken away to Russia. Today there is a strictly guarded base of the elite regiment "Tiger" of the Ukrainian police on its territory. Most of the tunnels were re-equipped for munition storage.
