Oulu Prison (Oulun vankila)

Oulu Prison (Finnish: Oulun vankila) is a correctional facility located in the Myllytulli neighbourhood of the city of Oulu, Finland. Institutional sources record that the prison has 80 places (ten reserved for female prisoners) and reported a mean population of 87 in 2012. The supplied archival documents referencing Oulu (including CIA reading-room files) do not discuss the prison's history, construction date, ownership changes, or notable incidents relating to the facility itself. The research corpus supplied contains no reports of hauntings, apparitions, poltergeist activity, or any other paranormal phenomena connected to Oulu Prison. No named supernatural entities, local oral traditions, or folkloric narratives about the prison appear in the provided sources. Explanatory frameworks (residual haunt, poltergeist, etc.) are therefore absent because there are no documented phenomena to explain in these materials. Cultural or historical significance beyond its institutional role as a small city prison is not established in the supplied documents. Some CIA archival items mention the city of Oulu in unrelated contexts (for example a Finnair hijacking originating in Oulu in 1978) but do not link those events to the prison. The current operational status of the facility beyond the 2012 population data is not specified in the provided sources; further inquiry into Finnish-language records or local archives would be required to update that information.
