Korsholm (Mustasaari) is an old municipality with an eye on the future  The municipality has a history dating back to 1348. This was when the parish was mentioned for the first time in writing in a royal letter concerning freedom of commerce.

The history of Korsholm is largely also the history of the City of Vaasa and Ostrobothnia. The granite cross at the ruins of Korsholm Castle (Chrysseborg) stands as a symbol of Christianity’s first conquest in the region. The castle was built in the 1370’s to support the country’s defence. From here, the whole of Ostrobothnia was ruled for several centuries, and occasionally also what is now Västerbotten in Sweden.

In the 1550’s, Gustav Vasa had a royal estate built, i.e. a model farm for the farmers of the region.

In 1606, the parish’s church village status was elevated to a city and was later given the royal name Vaasa. A fire in 1852 devastated most of the city. During the reconstruction, the city was moved to its current location. Old Vaasa with its Korsholm castle ramparts and ruins of St. Mary’s Church from the 14th century is today a popular tourist destination. There is also the old Court of Appeal building, which escaped the fire, and has served as Korsholm Church since 1863.

Korsholm today

The Korsholm municipality known today was formed in 1973 through a merger of the five nearby municipalities of Björköby, Korsholm, Kvevlax, Replot and Solf (Björköby, Mustasaari, Koivulahti, Raippaluoto and Sulva). Of the now approximately 19,500 inhabitants, 69% have Swedish and 29% have Finnish as their mother tongue.

Korsholm is an archipelago municipality – the municipality has an area of approximately 3,600 km², of which the land area is 846 km².

Thanks to constant land uplift, the municipality’s land area increases by about 20 hectares per year. The rate of land uplift in the region is among the highest in the world.

Korsholm is in many respects a municipality with contrasts. It has an archipelago, a sea and a mainland, urban and sparsely populated areas, industrial areas and agricultural fields as well as historical monuments.

Korsholm is an appealing  municipality to move to. The services and infrastructure here are constantly being developed to meet the needs of residents.

We have some of the most pleasant living environments in the country.
