It's amazing how full of history London is.
Today I did a steady pace five miler (7:15 to 7:30 pace) along a route I've done a few times recently: down to Tower Hill, east along Cable Street (runs parallel and between The Highway and Commercial Road) and back via Shadwell Basin.
So when I get back to the office I want to double check Cable Street isn't actually spelt Cabel Street (well you never know). And the first result returned from Google is for the Battle of Cable Street. I had absolutely no idea (I wonder how many other people live on that street and have no idea either).
