An important goal of the Holocaust Memorial Centre is to research and document the history of the Roma Holocaust at an academic level — Andor Grósz highlighted, emphasising that the temporary exhibition on display at the institution, entitled “On the Path of Memory — Narratives and Traces of the Roma Holocaust,” offers visitors a comprehensive introduction to the Porajmos experience of various Roma communities. Based on a resolution passed at the Paris congress of the World Romani Union, August 2 has been observed worldwide since 1972 as the day of remembrance for Roma victims of the Holocaust. The date commemorates the night of 2–3 August 1944, when more than three thousand Roma were murdered by SS soldiers at the Auschwitz death camp. Smaller Roma groups were taken to German extermination camps as early as the spring of 1944, and in August, Roma labor service companies were formed. Historians estimate that between fifty thousand and seventy thousand Roma from Hungary perished as victims of the Holocaust.
