This is what the secret military unit of the Warsaw Pact looks like today. It has turned into ruins.

The base was established in the 1960s between Zimna Wódka and Olszowa in the Strzelce County in Opole Voivodeship. For about 30 years, it was a great secret and the facility was heavily guarded. However, after the fall of the Polish People’s Republic, the base lost its significance. Upon the military’s departure, it began to fall into ruin.
