This article discusses the history and attempts to create the memory of Thalerhof, a camp functioning during the First World War in Styria in the south of Austria. Most of his prisoners were Galician Ruthenians, especially representatives of the Russophile movement. During the three years of the camp’s existence, 16,400 internees passed through it, and 1,767 people lost their lives in it. While the history of the camp has been repressed from the memory of the Austrians, for the descendants of the victims it is still an undeveloped trauma. It is all the deeper because Thalerhof has become the subject of a dispute between the (Carpat-)Ruthenians and Ukrainians, because both sides of the conflict want to write the memory of him only within the framework of their own history. Thus, the camp in Thalerhof can be considered a typical divided memorial site
