The border between Finland and Russia was somewhat conditional for centuries. Before Finland’s independence, people often crossed the border for visiting the neighbouring villages, for trading, studying, or looking for a job. Only after the independence, the border truly became an obstacle to such everyday activities. During the Cold War, Finns were altogether prohibited to visit the Karelian Isthmus on the Soviet side. After the collapse of the Soviet Union, the border is open again, and cross-border visits are once again possible on regular basis.
In the 1920s, the recently closed border fascinated Finns. Many fears and myths were associated with it. Tourists, members of the White Guard and Lotta Svärd made trips to the Rajajoki border river. In the late 1930s, when the feeling of war was in the air, several notable foreign guests were taken to the Isthmus and Terijoki to inspect the border and see how it is guarded.
