The concentration camp of Amersfoort was with Vught and Westerbork one of the three concentration camps operated by the Nazis in Holland. For the German administration, Amersfoort was a Police Camp. Not much information is recorded concerning living conditions in this camp. What is known is that thousands of Dutch and Belgian civilians received harsh and cruel treatment at the hands of the Nazis and hundreds were executed at this camp.
In the early stages of Nazi measures against the Jewish people camp Amersfoort also was used to confine and then deport the Jews of Amersfoort. In 1941, 820 Jews lived in the city of Amersfoort. The municipality at first resisted anti-Jewish measures, but could not prevent the removal of Jews from Amersfoort's economic and cultural life. By 22 April 1943 most of the Jewish population in camp Amersfoort was transferred to concentration camp Vught, another of the Nazi camps in the Netherlands. From there they were deported to Poland for extermination. After that date the camp took on the identity of a notorious concentration camp. Life was extremely harsh and torturous for the inmates. Many escapees were shot by the SS. Many Dutch Jews joined others in escape attempts. Most were shot by the SS, however some made good their escape and joined Resistance Fighters which were active in every Nazi occupied country. Capture by the SS meant torture and certain death.
At the time of liberation only 415 survivors were counted. Hardly any of the survivors were Jews.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
