 The three rooms used for this purpose (colloquially referred to as the "sekyrárna", or "axe room" in Czech) have been preserved, and serve as memorial that is occasionally accessible to schools and public.After the war, many executions of Nazi officials and collaborators took place in the prison, including the hanging of Karl Hermann Frank, as well as Kurt Daluege, the SS chief responsible for the Lidice and Ležáky massacres.Initially, the executions of Nazis were public, but this practice was soon abandoned.
