From Wikipedia, the free encyclopedia.
The Karelian Isthmus is the narrow land, now in Russia, between the Gulf of Finland and Lake Ladoga. The city of Vyborg and the town of Priozersk are situated on the eastern end of the isthmus. In south-west it reaches to Saint Petersburg.
Due to the rich soil, rich fishing waters and the proximity to Saint Petersburg, the Karelian Isthmus became the wealthiest part of Finland once the industrial revolution had gained momentum in the 19th century.
In World War II the isthmus became known to the world as one of the few areas with fierce fightings during the "Phony War" (Winter of 1939-40). It was annexed by the Soviet Union after the Winter War.
