Museum "Under the Clock" is a sad reminder of the history of the period of terror during the Second World War, devoted to the martyrdom of Grey Ranks and young people from the years 1939-1945 and the NKVD prisoners from AK and WiN.
The museum is located close to the Catholic University of Lublin. This building with the clock, which is on the top, was during the Second World War, the place of hearings and enforcement of the Gestapo.
