Bombing of Ulm in World War II

Ulm, for its size, was the most heavily bombed city of south Germany during [World War II]].

The heaviest air raid was on December 17, 1944, killing and injuring hundreds. About 25,000 people were left homeless. By the end of the war, 81% of the city center was destroyed. Only 1,763 out of 12,756 buildings were intact. 4,400 Ulmers died. But the Ulm Münster (cathedral) still towered above the ruins.Water-filled bomb craters covered the ground, following the rain. The rubble was so thick that walking was almost impossible.
