Strafgefängnis Mürau was located in the Higher Regional Court District of Leitmeritz (Litomierzyce), with a capacity for 500 male prisoners. After the takeover of the prison by the German justice system, between 1939 and 1941 it was intended for prisoners sentenced to up to one year's imprisonment. Subsequently, the Ministry of Justice of the Third Reich (to which the prison system was subordinate) ordered that tuberculosis patients be incarcerated in the prison. Poles accounted for two-thirds of the prisoners between 1943 and 1945, with Czechs being the second nationality in terms of the number of inmates. Yugoslavs, Slovaks, French, Italians, Austrians and Germans, among others, were also brought here. It is known that during the period of the prison's operation, 666 prisoners died - 516 Poles and 137 Czechs, who were buried in the prison cemetery. Tuberculosis, inadequate food rations and the harsh prison regime mainly contributed to the high mortality rate. With the end of the war, evacuation transports arrived in Mírov from, among others, Těšín prison. As part of the evacuation, the Těšín Special Court (Sondergericht) was also moved to Mírov and sentenced a total of 12 people to death in Mírov - on 4 April 1945 at 5:12 a.m. two Poles were shot: Alojzy Sikora from Sucha Górna and Anastazja Michalska; on 13 April 1945 Alojza Sniegoniová (née Lakota) from Orlová near Karviná was shot. The prison was liberated on 7 May 1945. The dead prisoners were buried in the prison cemetery in individual graves. After the war, the remains were moved to a mass grave, where in 1967 a magnificent monument was erected, consisting of a figure of a suffering man set against a high wall, bearing plaques with the names of the victims, the coats of arms of Poland and the Czech Republic, and a memorial inscription. Next to the grave is the symbolic grave of Hungarian national activist János Esterházy, who died in 1957 in Mírov prison. The memorial has been recognised as a cultural monument of the Czech Republic. The grave and the memorial are accessible via a dirt road diverging from the main road in Mírov just behind the Municipal Office to the right downhill (turn at the memorial plaque). In 2003-2005 the cemetery area was reconstructed with funds from the Mírov Municipality, the Union of Hungarians in the Czech Lands, the General Consulate of the Republic of Poland in Ostrava and the Státní fond životního prostředí České republiky.
