Archaeological investigations in BełżecBased on the data collected by the Holocaust Education and Archives Research Team, the investigations carried out in Bełżec were different of all the investigations carried out previously. At first, the importance of this site and the enormous number of victims didn't seem like it could be much of the story. The latest investigation and search revealed evidence of the massive massacres that took place there. This archaeological research also confirmed the existence of evidence demonstrating that there was a Nazi attempt to hide the scale of the crime. Before the fourth investigation, carried out between 1997 and 2000, three other investigations took place in 1945, 1946 and 1961. The last investigation is the result of the agreement between the Council for the Protection of the Memory of Combat and Martyrdom in Warsaw, in association with the United States Holocaust Memorial Council and the United States Holocaust Memorial Museum in Washington, DC. The methodology applied in the four surveys was more or less similar. This involved “delimiting the area to be examined according to a fixed grid system at intervals of 5 meters (knots). Exploratory drilling to a depth of 6 meters was carried out; obtain core samples of geological strata. In total, 2,001 exploratory archaeological drillings were carried out and made it possible to locate 33 mass graves of different sizes.
