It was part of Prussia beginning in 1815. The city was heavily bombed during the war, which led to a 93% reduction in population due to evacuations and the destruction of around 80% of the ancient city center. The post-war reconstruction resulted in a diverse cityscape, restoring many major historic landmarks such as city gates and churches (31 of which are Romanesque). Presently, around 25% of the buildings in the city are from before World War II, and there are approximately 9,000 historic buildings.
