So they say, but nobody in the City thinks these things. My candidate for the true centre is the London Stone, legendarily set in place by King Lud himself when founding the city and whom it is named after. It's located at 111 Cannon Street, across the road from Cannon Street station.

No Londoner would write 'the City' to mean anything other than 'the City of London' (i.e. excluding the rest of the 'city') - which makes it unclear to me how to read your comment, especially given other familiarity/information. Are you saying 'nobody' (I'm not being pedantic on that, hence quotes) living/working in the City sees it as anything other than another borough? (But implicitly others do?)

People in `the City`/Square Mile would say that the center of London is the City of London, the historical center of London. In general Charing Cross (in my view) is more of a 'Geographical Center', as London has slowly expanded over time. It's kind of the middle of Zone 1 -https://en.wikipedia.org/wiki/London_fare_zones

I think it's down to how one interprets the question. Some might see the question as: "Where did London start/expand out from" and other "If I were to look at London now, where is the center of where you would consider London".

I agree with you, it was GP's.. I think disagreement that I was trying to understand - I've edited the quote in to my comment to hopefully make that clearer.

[simonh]

I meant the square mile, yes.

[BerislavLopac]

Yes, except that the London Stone was first mentioned around 1100 AD.

[simonh]

True, but then hardly anything in Britain was mentioned much before then.

[BerislavLopac]

I'm sorry? O.o

[simonh]

Britain before that time was extremely poorly documented, and almost all the (few) documents that did exist were lost.
