The exact location of the collection camp within the Radiotrh area kept changing during the occupation; in the autumn of 1941 it was located in exhibition pavilions U1 and U5. The commercial rental of the actual space was paid for by sale of property confiscated from the Jewish people being deported.
The collection of Jews from Prague for the first transport began on October 13, 1941. Three days later, 1,000 people were sent to the Łódź ghetto. The majority of transports from Radiotrh were destined for the Terezín ghetto. Later, the camp was also used for the deportation of people labeled as Mischlinge, children who, according to the Nazi racial law, had Jewish and non-Jewish ancestry. The deportees came from the Protectorate of Bohemia and Moravia, the German-occupied, nominally independent territory of former Czechoslovakia roughly corresponding with the historical lands of Bohemia and Moravia, without their Sudetenland borderlands.
The last transport left Radiotrh in mid-March of 1945. At least 45,513 persons passed through the camp at Radiotrh, 37,667 of whom did not live to see liberation. At the very end of the war, the area of the New Exhibition Grounds was set on fire, and all its traces were gradually removed. The Parkhotel complex was built on part of the property. After the fall of Communism, a memorial plaque was installed on one of the property walls.
