The Vaasa prison was designed by C. A. Setterberg and was built during 1861–1863 to be as close as possible to the court of appeal for easy transportation of prisoners to face the justice. Some of the most notable dwellers of Vaasa prison have been the knife junkers Antti Rannanjärvi and Antti Isotalo. The knife junkers were feared troublemakers in Southern Ostrobothnia from 1820s to 1880s.
The editor-in-chief and newspaper publisher Edvin Sundquist managed to escape the prison during the night of Midsummer in 1916. He was part of the Jäger Movement and worked years as the editor-in-chief of Vasabladet.
