Barely 20 kilometres northeast of Budapest lies Kistarcsa, where the Hungarian regime had established a detention camp for communists during the thirties. When the Germans occupied Hungary in march 1944, the germans took over the camp and detained Jews from Budapest before being deported to, for instance, Auschwitz. The first deportation to Auschwitz departed on April 29, 1944, with about 1,800 Jews. In total, just under twenty transports departed from the camp to Auschwitz before transports were halted in July. 1944.

Current status: Partly preserved/demolished with monument (2010).

My comment:

Several of the camp’s barracks were renovated after the war for other purposes while others remain and are in a state of decay.
