Exploring Finnish WW2 Bunkers & overnight camping at Harparskog Fortification Line (2/3)

The Harparskog line was a Finnish fortification line at Hanko peninsula, it was built after the Winter War (1940), in order to defend Finland against a possible attack from the Soviet naval base. Soviet union acquired the naval base at Hanko peninsula, because of the winter war peace treaty (1940). One of the many tough conditions included: Finland had to lease Hanko peninsula to the Soviet Union as a naval base, for the next 30 years! The lease didn’t last for long. When the Germans occupied Estonia in September 1941, the Soviet naval base at Hanko was shut down and evacuated. The planning of the Harparskog fortification line, at the new border, began shortly after the end of the Winter War (1940). 40 bunkers of various types were built. After the Finnish Continuation War (1944), the bunkers were kept as a reserve in the event of military mobilization. The fortification line was also used for military rehearsal exercises, and the bunkers as weapons storages, until the end of the 1980s. Nowada
