Bomb Sight is a free, online, and interactive map of every recorded bomb site during the heaviest eight-month shelling of London in World War II.
Compiled by the University of Portsmouth and The National Archives using census data taken between October 1940 and May 1941, the map documents the scale of the Blitz in a new and visually arresting way. A proliferation of red dots marks the spot where each bomb landed. Previously, this information could only have been viewed in written format via the Reading Room at The National Archives. The locations of the bombs have been combined with photographs from the Imperial War Museum and memories taken from the BBC's WW2 People's War Archive to enable anyone to research the stories of those involved and affected by the war.
Architects interested in post-war urban-planning may be interested to learn that there is an Android app which, when a phone is pointed at a street scene, will display the bombs that fell nearby.
