Except for the Orel Peak Mass Grave, which is a former wartime Home Guard cemetery, all of the concealed mass graves in Ljubljana were created in the immediate aftermath of the Second World War, after British forces forcibly repatriated Home Guard soldiers that had fled to Austria to Yugoslavia from camps in Bleiburg, Lavamund, Rosenbach, Viktring (a district of Klagenfurt), and elsewhere. Many of the returnees were held at the St. Stanislaus Institute in the former village of Šentvid, just outside Ljubljana, which was used as a prison by the Partisans. Some died in Šentvid, but most were transported elsewhere and murdered.
