Bunker No. 42 (Moscow, Russia)
A five-minute walk from the Taganskaya (Koltsevaya) station stands an inconspicuous two-storey mansion. It differs from ordinary mansions primarily in that there are no windows on the ground floor. There are no windows for a simple reason — the only purpose of this house was to hide a 6 m thick concrete dome. He, in turn, protects the shaft leading down to 60 m.
