 Amersfoort was a transit camp, whence prisoners were sent to places like Buchenwald, Mauthausen and Neuengamme concentration camps.It was on July 15, 1942, that the Germans began deporting Dutch Jews from Amersfoort, Vught and Westerbork to concentration camps and death camps such as Auschwitz, Sobibor and Theresienstadt.The remaining watchtower, as can be seen on the commemorative place, was built around April/May 1943, when the expansion of Kamp Amersfoort was completed and prisoners could be held there again.
