Vilniaus sunkiųjų darbų kalėjimas (Vilniaus Lukiškių kalėjimas)  

The prison became more notorious during the Nazi occupation of Lithuania, when it was used by the Gestapo and Lithuanian Security Police as a holding cell for thousands of Jews from the Vilna Ghetto. The majority were taken to the outskirts of Vilnius and executed at Ponary (Paneriai). When Soviets reoccupied the territory in 1944, the prison was returned to the NKVD.
