Vita Björn Prison Museum

Closure of the Vita Björn remand prison in 1975 marked the end of a centuries-long tradition of incarceration at Kastelholm Castle. The area has seen both primitive prisoner boxes, dungeons in the castle and a jail located on the other side of the sound.

Vita Björn served as both jail and prison for nearly 200 years. Today, the facility serves as a prison museum, where you can experience the development of prisoner treatment from the end of the 1700s to 1950, from a time when shackles and chains were part of the prisoners’ everyday life to a more humane approach to incarceration. The Vita Björn building is the oldest of its kind in Finland. After its closure, the prison was totally restored, opening in 1985 as Finland’s first official prison museum. Restoration of Vita Björn was done by the Kastelholm labour colony, which was later disbanded.
