Salpa Line in Voisalmi
In the south of the Voisalmi Island, there are four machine gun bunkers with steel reinforced concrete, and you can enter one of them, number 5. Around and behind the bunkers, are the battle and communication trenches that were dug into the ground and rock. On the west side of Voisalmentie Road, near Bunker 5, the trenches have been reinforced with concrete and there are also three gun nests made of concrete, one of which is covered. There are very few concrete reinforced battle trenches along the Salpa Line. There is a stone anti-tank barrier to the south of the stations.
