Sestroretsk

Just at the former Finnish-Russian border at Sestroretsk (finnish Systerbäck) lies a large bunker that was part of the Soviet defense line that ran along the finnish-russian border on Karelian isthmus. The Bunker and the lin defense line began to be built during the thirties to defend an attack against Leningrad. At this time Leningrad was only about twenty kilometres from the border and thus extremely exposed. It was not necessarily a Finnish attack that the russians feared, but more that German troops would have access to Finnish territory to attack the Soviet Union from Finland.
