Before the Second World War , Wjartsilja belonged to Finland and was called Värtsilä. The village, which belongs to the Tohmajärvi municipality , developed into an important industrial center in the 19th century. The beginning of industrialization in Wjartsilja was marked by the construction of a sawmill in 1834. The industrialist Nils Ludvig Arppe took over this two years later and founded an ironworks in 1852 . The Finnish Wärtsilä Group emerged from the Arppe estate, which bears its name after the place and which today manufactures marine engines. Due to the industry, the place grew strongly, so that in 1920 the municipality of Värtsilä was separated from Tohmajärvi. After the Finnish-Soviet winter war , Finland Wjartsilja ceded to the Soviet Union . In the Continuation War, the Finns recaptured the place in 1941, but had to cede it again after the end of the war in 1944. Wjartsilja was burned down by the Soviet troops when they withdrew at the beginning of the Continuation War, but was rebuilt after the war and again developed into an industrial town.
