Seinäjoki (pronounced 'SAY-na-yoh-kee') is a city in Finland. It is the main city of the South Ostrobothnia region. You can find Seinäjoki in the western part of Finland, right by the Seinäjoki River.

About 66,000 people live in Seinäjoki. The larger area around it, called the Seinäjoki sub-region, has about 132,000 people. This makes Seinäjoki one of the biggest cities in Finland.

Seinäjoki is located 80 kilometres (50 mi) east of Vaasa and 178 kilometres (111 mi) north of Tampere. It is also 193 kilometres (120 mi) west of Jyväskylä and 324 kilometres (201 mi) southwest of Oulu.

The city started around the Östermyra bruk iron and gunpowder factories, which were built in 1798. Seinäjoki became a municipality in 1868. It grew into a market town in 1931 and then a full town in 1960.

In 2005, the nearby municipality of Peräseinäjoki joined Seinäjoki. In 2009, Nurmo and Ylistaro also became part of Seinäjoki. The city itself is growing, but the population in the surrounding areas is slowly decreasing.

Many important public buildings in Seinäjoki were designed by the famous architect Alvar Aalto. These include the city hall, the city library, and the Lakeuden Risti Church. The Seinäjoki Airport is located nearby in Ilmajoki, about 11 kilometres (10 mi) south of the city center. The Seinäjoki railway station opened in 1883.

History of Seinäjoki

Early Settlement and Growth

People started living in the Seinäjoki area in the early 1500s. By the 1550s, there were at least three main houses: Marttila, Jouppi, and Uppa. Another house, Jouppila, was also built around this time. All these homes were located along the river.

Seinäjoki was originally part of the Ilmajoki church area. However, the roads to the Ilmajoki Church were often in bad condition. So, in 1725, people from Seinäjoki and nearby Nurmo built their own chapel. This led to the creation of the Nurmo chapel town in 1765.

Seinäjoki became part of this new chapel town. In 1798, the chapel parish of Peräseinäjoki was founded. In the same year, the Östermyra steel mill was built by the Seinäjoki river.

Becoming an Independent Municipality

In the 1850s, people in Seinäjoki wanted to separate from the Nurmo church parish. Even though people in Nurmo disagreed, the Finnish Senate allowed Seinäjoki to form its own chapel group in 1863.

Seinäjoki gained its own local government in 1868. By 1900, it became a fully independent municipality.

The Importance of Railways

Seinäjoki grew a lot because of its important railway connections. The railway connecting Tampere and Vaasa opened in 1883 and passed through Seinäjoki.

Later, the Kokkola track opened in 1885, and the Kristinestad track in 1913. These railways made Seinäjoki a very important railway hub in Finland. In the early 1970s, a direct railway between Tampere and Seinäjoki was built, which helped the city even more.

After the Winter War and Continuation War, some people who had to leave their homes in Jaakkima and Lumivaara moved to Seinäjoki.
