This fascinating map was created by The Violence Research Centre (VRC), based at the Institute of Criminology, University of Cambridge to answer the question "How violent was medieval London?'. Here's their introduction:
Each pin represents the approximate location of one of 142 homicides cases in late medieval London. Click on a pin to open a window that displays the story behind the event, based on the original record produced by the Coroner. For more information on how to use the map, visit this page. If you are referencing our map, please read the note at the bottom of the page. You can listen to the launch lecture here.
