From 1933 to 1935 , a concentration camp primarily for political opponents of the regime was established on the Kuhberg , one of the hills surrounding Ulm . The Jews of Ulm , around 500 people , were first discriminated against and later persecuted ; their synagogue was torn down after Kristallnacht in November 1938 . The sole RAF strategic bombing during World War II against Ulm occurred on December 17 , 1944 , against the two large lorry factories of Magirus-Deutz and Kässbohrer , as well as other industries , barracks , and depots in Ulm . The Gallwitz Barracks and several military hospitals were among 14 Wehrmacht establishments destroyed . The raid killed 707 Ulm inhabitants and left 25,000 homeless and after all the bombings , over 80 % of the medieval city centre lay in ruins
