Following the end of the Second World War, Sobibór and its history had been forgotten for over twenty years. The first proposals to commemorate the Sobibór extermination site were put forward not earlier than by the 60’s. It was related with the lawsuits against the Nazi perpetrators in Hagen (Germany) and Krasnodar (the then USSR).
The author of the first commemoration is engineer Romuald Dylewski. The most crucial elements of the commemoration were a monument (by Mieczysław Welter) depicting a woman with a child standing near a column alluding to gas cahmbers, and a symbolic mound where bodies were burnt and buried. The ceremonial unveiling of the monument, organized by the Regional Committee for the Protection of Struggle and Martyrdom Sites in Lublin, took place on June 27, 1965. However, the then form of commemoration did not reveal the whole truth. There was information on the memorial plaque that about 250,000 Soviet prisoners of war were killed in the camp.
In the first half of the 80’s the Sobibór monument was rebuilt. The sulpture of the women with the child was moved away from the column. It has not changed since that time.
In 1993, in the 50th anniversary of the outbreak of the revolt in Sobibór, the Museum of the Former Death Camp was set up, as a branch of the Museum of Łęczyńsko-Włodawski Lake District. The ceremony was participated by many former prisoners. At that time, a new multilingual memorial plaque was unveiled informing on the extermination of 250,000 Jews.
Initiated by social organizations Bildungswerk Stanislaw Hantz from Kassel (Germany), Stichting Sobibor (Holland), and the Society for Commemorating Sobibór (Poland), a new form of commemoration – “Remembrance Alley” was created. Symbolic stones are set by the road sustaining names of Sobibór victims and commemorating given groups of prisoners (e.g. Jews from Chełm, Włodawa or Izbica).
In May 2012, the Museum of the Former Death Camp in Sobibór became a branch of the State Museum at Majdanek. Owing to that fact and archeological research being conducted on the site since 2000, action has been taken to create a new form of commemoration.
