In his contribution, the author deals with the issue of juvenile convicts in Slovenia who were serving their sentence of deprivation of liberty with forced labour and deprivation of liberty in the period 1945–1953. The emphasis lies on listing the penal institutions in which the juvenile convicts served their custodial sentence. Furthermore, the regime in such institutions is described. The author finds that until 1953 juvenile convicts served the two types of sentences alongside adult convicts in the same penal institutions and were subject to the same regime. Their situation began improving only after 1951, when they were separated from the adult convicts in the correctional facilities in Maribor and Rajhenburg. They were finally completely separated in July 1953, when they were relocated to the Radeče Correctional Facility where a special department was founded specifically for them.
