I've been talking about some of London's hidden rivers recently and how ten rivers used to flow into the Thames in and around the centre of London. Way back when, if you were travelling you were at greatest danger at the points where travellers were concentrated by the landscape. You would often find robbers at bridges, the Knight's Bridge (which crossed the river Westbourne) was one such. Nothing changes, does it?
For those who don't know, Harrods is in what is now called Knightsbridge.
