The Montelupich Prison, so called from the street in which it is located, the ulica Montelupich, is a historic prison in Kraków from early 20th century, which was used by the Gestapo in World War II. It is universally recognized as "one of the most terrible Nazi prisons in [occupied] Poland". The Gestapo took over the facility from the German Sicherheitspolizei at the end of March 1941. One of the Nazi officials responsible for overseeing the Montelupich Prison was Ludwig Hahn.
