found: The Vyborg bang 2, 1994:p. 1 (Vyborg is located at 25 kilometers from the Finnish-Russian border and 130 K from St. Petersburg. From the early Middle Ages until 1809 Finland was part of the Swedish Kingdom, and the border town of Vyborg most of the time belonged to the Swedes, being at times taken over by the Russians. From 1809-1917 Finland was an autonomous great duchy of the Russian Empire, and Vyborg was most of that time part of the Finnish autonomous area. From 1917 until WWII, Vyborg was part of independent Finland. After the two wars between Finland and the Soviet Union (1939-1944), Vyborg and the surrounding areas were annexed to the Soviet Union, and the whole population was evacuated to Finland. Today Vyborg's population is basically Russian)
