Background

The Suomenlinna prison is an open prison in Suomenlinna, Helsinki, Finland, founded in 1971. It was previously known as the Suomenlinna penal colony. The prison is located at the southern tip of the island of Iso-Mustasaari. The prison was founded to help in the repair and restoration work of the Suomenlinna fortress; the prison co-operates with the Governing Body of Suomenlinna belonging to the Finnish Ministry of Education. Prisoners in the open prison, nicknamed Konnala (roughly translated as "Crook-land") work on weekdays in various jobs all over the island, under supervision.
