Tokyo, Moscow, London, Belgrade, Baghdad have been destroyed waaay to many times.
The former city even has a term for it, the 'Flowers of Edo' as on average every 25 years over the past 5 centuries the city was visited by a vast catastrophe, often a conflagration lighting up the horizons from afar.
Even to this day it's infiltrated the cultural mindset - society, design and laws now encourage buildings to be seen as temporary (and the birth of functionalism, which the early modernists visited to study).

The last time Tokyo was destoyed was in the 1945 air raids, the world's worst ever that killed over 200,000. It became the most destroyed ever piece of urbanity, where one could see across
8 straight miles of levelled cityscape.

The city of Kaifeng (pop 5 million), once the world's largest, has been flooded and destroyed by the Yangtze River no less than 300 times. There's so much history in the clay of the former capital that it's the only major city in China which doesn't have highrises and skyscrapers, as every building would involve major, expensive, delaying architectural finds.
