On May 11, the United Kingdom will mark the 75th anniversary of “The Longest Night,” the final horrible night of the Blitz—an eight-month-long aerial bombing offensive launched by Nazi Germany during World War II. More than 40,000 British civilians were killed in the Blitz, 1.5 million Londoners were left homeless, and the city’s landscape was left shattered. Below, Getty Images photographer Jim Dyson recently traveled to locations across London to make comparisons between scenes from the Blitz and present-day images, laying one on top of the other.
