It was set up on the area of Károly Barracks immediately after the siege of Budapest. This was the first big internment camp after the war from where internees were taken to outside work, mainly rubble cleaning and construction work. In autumn 1946 the camp became the Central Internment Camp of the Budapest Headquarters of the Hungarian State Police.
The 4-5,000 inhabitants were devided into five regiments on the basis of sex, education, job, and nationality. New arrivals were first of all shaven bald then examined for lice and after a bath disinfected.
At the end of April 1949 the camp was evacuated and moved to Kistarcsa.
