The tragedy of the aerial bombardment of WWII is that bombing was not precise enough to hit specific buildings or landmarks. The targets was on the level of a whole city. This is part of the reason the number of civilian casualties in WWII were so huge compared to previous wars. All parties in the war did this, but the allied were simply more effective due to air superiority, especially towards the end of the war. This is why cities in Germany where totally destroyed while London was not.
