Seinajoki - City of Finland

Seinäjoki is a city located in Southern Ostrobothnia, Finland. Seinäjoki originated around the Östermyra bruk iron and gunpowder factories founded in 1798. Seinäjoki became a municipality in 1868, market town in 1931 and town in 1960. In the beginning of 2009, the neighbouring municipalities of Nurmo and Ylistaro were consolidated with Seinäjoki.
