I love finding these types of bits of information...
It would appear that something that has been a core and central part of London since Roman times is now no more than a little know piece of rock behind a metal grill - the London Stone.
I found the story of the London Stone a few days ago and, almost more out of disbelief than anything else, had to go and find it for myself. How many times must I have travelled past the London Stone without ever noticing it, let alone knowing it was there.
And yes, there it was, mythical, legendary, known to greats like Shakespeare and Dickens, unknown to millions of Londoners.
I just hope that this piece of London's history isn't lost to us all!
