During the Second World War, in addition to the Jews, the Roma were also persecuted. At the end of the war, they were gradually concentrated in concentration camps, from where they were sent to death camps. It was 1945 when a typhus epidemic broke out in the concentration camp in Dubnica nad Váhom. On 23 February, the Nazis loaded all the sick Roma onto a lorry under the pretext of taking them to the hospital in Trenčín. They never arrived there.
Shortly after the war, workers from the ZVS made a cross out of artillery ammunition and placed it on a mass grave. Next to it, in 2007, the civic association In Minorita installed a monument with the names of the murdered. The bodies of the victims were exhumed, identified and later placed in separate graves. The President of the Slovak Republic Zuzana Čaputová came to honour their memory on the 79th anniversary of this inhumane act.
