The Blitz, the German bombing campaign against Britain during the Second World War, had a profound impact on London. 

From September 1940, the German Luftwaffe dropped some 20,000 bombs on the city, killing thousands, and leaving many more homeless. But for all its human cost, a 2021 research paper has suggested that the London Blitz may also have had a significant impact on how the capital would develop in the years after the war.

Economists calculated that, had the Blitz not occurred, London’s Gross Domestic Product (GDP) would be 10% lower, or £50 billion worse off every year.
