Like every nation, the Czechs have to face their history, good and bad. There were 220 labour camps during the war established by law, some of them before the Nazi occupation of the Czech lands. Many of the camps, such as Lety, were staffed exclusively with Czech personnel who received only occasional visits from German officers.

In 1993, on the basis of previously inaccessible records seized by the Soviet Army at Auschwitz, very precise documentary evidence of the construction and operation of the gas chambers has been provided.
