The story
Kontiolahti originally belonged to the parish of Liperi. It became an independent municipality in 1873. The flood nuisance of Lake Höytiäinen and the desire for water abandonment inspired residents to try to build a canal to lower the water level, but the dam broke uncontrollably in 1859, and the landscape changed dramatically. After World War II, the Ruskeala's migrants were stationed in Kontiolahti.
