Imatra is a town and municipality in eastern Finland, Imatra was founded in 1948 on the territory of three municipalities – Jääski, Ruokolahti and Joutseno. Finland ceded 11% of its territory to the Soviet Union after the Winter War. Jääski lost 85% of its territory and it was decided that a new municipality, Imatra, shall be established on the remaining 15% of Jääski and some areas of Ruokolahti and Joutseno. This is why the Imatra coat of arms has three flashes – in honour of those previous municipalities that granted areas to it. Imatra is dominated by Lake Saimaa, the Vuoksi River and the border. It gained its municipal charter in 1971.
