Dresden: 23% of industrial buildings, 50% of homes, 25,000 dead: https://www.bbc.com/news/world-europe-51448486

Warsaw was closer, but only 85-90% of its buildings were destroyed by the Nazis: https://en.m.wikipedia.org/wiki/Destruction_of_Warsaw

The statistic I heard was “more than any city in wwii”. I figured that Hiroshima (67%) years or Nagasaki (37%) were worse.

Gaza crossed 90% of all buildings in May, so I shouldn’t have qualified my statement with the word “European”.

Edit: I found one partial counterexample: The firebombing of Tokyo killed about 10x more people than Israel did during this conflict, but didn’t do nearly as much damage (as a percentage) to buildings: https://www.britannica.com/event/Bombing-of-Tokyo
