During the second world war, German forces dropped 28,000 bombs and almost 3,000 V1 flying bombs and V2 rockets on London. Nearly 30,000 people were killed. The damage to the built environment was extensive.
Within the London County Council area (roughly covering today’s inner London), more than 73,000 structures were totally destroyed. Local surveyors, construction workers, architects and engineers documented the destruction as it happened on hand-coloured maps, which are now held at the London Metropolitan Archives. Some 43,400 structures recorded on these maps were categorised as “damaged beyond repair”.
