Revealing the transformation of Britain's most important city: her capital, London. Starting with amazing Luftwaffe aerial photographs of the very first bombs of the Blitz falling on a vulnerable city, the programme tracks the changes that came out of five years of bombing. Comparing exhaustive footage of London in the 40s with the city of today, the team see how great plans for urban renewal were stillborn and, instead, London rebuilt itself in an ad hoc way along old street patterns. The only exception to this was the dramatic city that rose from the derelict docklands.
