The map is the centrepiece of a small free exhibition at the London Metropolitan Archive in Finsbury, which closes on 29 March. 18 maps, covering the old Metropolitan area of London (i.e. no further east than the Lea Valley!) have been reproduced onto panels and tiled together to create the map. Some other highlights of the exhibition include a wall of photographs of the devastation at Smithfields Market, following a direct hit by a V2 rocket.
The map is a dasymetric map, in the style of Charles Booth’s Poverty Map (and my modern update) where individual buildings are coloured in according to some kind of attribute, in this case bomb damage. Black indicates completely destroyed, while purple shows damaged beyond repair and red shows buildings that are severely damaged but which might be salvageable. Green shows sites where rubble was being taken to. Large circles show V2 bomb sites and small circles show V1 bomb sites, although the map is not comprehensive.
Looking at the map as a whole (the section above is only covering the Bloomsbury area) it is striking how much more damaged the East End of London was, compared to the West End, and also the huge swathe of damage running through the western half of the City of London (showing up in purple in the picture below) where little was left standing – except St Paul’s Cathedral.
