Helsinki County Prison

It was established in 1837 by Tsar Nikolai I[1] by the side of the Helsinki Crown Prison, which had operated from 1749.

During the Second World War, the prison was directly hit by an air strike on 6 February 1944.

At the end of the war, some well known convicts from the War-responsibility trials in Finland were kept in the prison, including President Risto Ryti[4] and Prime Minister Väinö Tanner.

[5][6] The Estonian-born writer Hella Wuolijoki[7][8][9] was there for high treason during World War II.

Another inmate of note was Martta Koskinen, a seamstress and communist spy convicted of high treason who was executed by a firing squad on September 29, 1943.
