During the Second World War, was used for the detention of Social Democrats, Communists, and other political prisoners. Around 200 died here; more died in April 1945, when the Nazis sent the prisoners on long marches, fearing the Allied advance. Just after the war, Hamelin prison was used by British Occupation Forces for the detention of Germans accused of war crimes. Following conviction, around 200 of them were hanged there, including Irma Grese, Josef Kramer, and over a dozen of the perpetrators of the Stalag Luft III murders. The prison has since been turned into a hotel. Executed war criminals were interred in the prison yard until it became full; further burials took place at the Am Wehl Cemetery in Hameln. In March 1954, the German authorities began exhuming the 91 bodies from the prison yard; they were reburied in individual graves in consecrated ground in Am Wehl Cemetery.
