A team at the University of Portsmouth has put together an interactive map of the London Blitz. Using historical data from several sources, they've mapped the location of every bomb that hit the city during World War II.
It's no small feat if only because of the huge number of bombs that fell during less than one year between October 1940 and June 1941.
The extent of the devastation is made very clear – you'll hardly find a place in the city not touched by the bombs.
You can explore the map in great detail, there's data on any of the listed bombs if you're interested in the info.
There's also an Android app with the same map and info, so you can explore it on your phone or better yet on your tablet.
