Soviet bunker in Salvador Andreu House, 17 Av. del Tibidabo, Barcelona, Spain

Keeping with bunkers, a modernist house that belonged to Dr. Salvador Andreu changed hands after the physician died. When the Spanish Civil War broke out, the house was taken over as the Soviet Union’s consulate. The Soviet Union was backing the Republican Forces, who were fighting to defeat General Franco’s forces, making the consulate a natural target, leading to a bunker being built with all mod cons, including toilets, a kitchen and a generator. The bunker can still be seen today.
