The building complex was built in 1889-1890 at the intersection of "ulica Sapiehy" (today "vulytsia Bandery") and "ulica Kopernika" on the project of architect Józef Kajetan Janowski. It is built in a Neo-Renaissance style and originally was designed for Austro-Hungarian Gendarmerie's main office in the city. The portion where the prison  was actually located was built soon after World War I in 1918-1920 when Lviv was part of the Second Polish Republic. The prison portion housed the Fourth Department of the State Police Main Commandant's Office, one duty of which included a fight against "anti-government" organizations such as Organization of Ukrainian Nationalists, Communist Party of Western Ukraine and others. Unofficially the prison was intended for political prisoners. In 1935 the investigating department of police were quartered in the building, while the prison was turned into a detention center. With the start of World War II in 1939 and  partition of the Second Polish Republic between Nazi Germany and Soviet Union, the prison was transformed into the NKVD Prison No.1 which was designed to accommodate 1,500 prisoners. The regional administration of NKVD took up quarters in the building. During the Nazi invasion of the Soviet Union in June 1941, the NKVD agents shot about 1,000 prisoners. During 1941-1944 the building was used as a Gestapo detention center and housed an office of Einsatzgruppen of Sicherheitsdienst (SD). From July 21 to 26, 1941 former Polish Prime Minister Kazimierz Bartel was imprisoned here.
