Although the inscription on the plaque by the ( side ) door of the prison in the 1939 photograph pictured at right actually reads , " Sicherheits-Polizei-Gefängnis Montelupich " , the name " Montelupich Prison " is strictly informal , based on common popular convention , even if it has now passed in that form into history . The Montelupich facility was the detention centre of the first instance used by the Nazis to imprison the Polish professors from the Jagiellonian University arrested in 1939 in the so-called '' Sonderaktion Krakau '' , an operation designed to eliminate Polish intelligentsia . In January 1944 , 232 prisoners from Montelupich were executed by a Nazi firing squad at Pełkinie . In late January or early February 1944 , Wilhelm Koppe issued an order for the execution of 100 Montelupich prisoners as a reprisal for the unsuccessful attempt on the life of Hans Frank . In the locality called Wola Filipowska near Krakow there is a monument commemorating the execution by the Nazis of 42 hostages , all Montelupich prisoners who died on the spot before a firing squad on 23 November 1943
