Regensburg is a city in eastern Bavaria. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremburg and Aysburg and the eighth-largest of all cities on the river Danube. From its foundation as an imperial Roman river fort, the city has been the political, economic, and cultural centre of the surrounding region. Later, under the rule of Holy Roman Empire.
The medieval centre of the city was made a Unesco World Heritage Site in 2006 because of its well-preserved architecture, being the biggest medieval city site north of the Alps.






Regensburg was home to both a Messerschmitt Bf 109 aircraft factory and an oil refinery, which were bombed by the Allies on 17 August 1943. Although both targets were severely damaged, Regensburg itself suffered minor damage from the Allied strategic bombing campaign, and the nearly intact medieval city.
