Walking thru the big parks
Brompton Cemetery (on the list for the next trip so haven't been there - https://en.wikipedia.org/wiki/Brompton_Cemetery)
London Wetland Center (again, haven't been, on the LIST, LOL https://www.wwt.org.uk/wetland-centres/london/wildlife/ )

Pretty much everything is non- royal unless you are traipsing round Buck House.

Nothing.

All of London is owned by the monarch. That's why when you buy a property you only buy a lease.

So everywhere you go in London is Royal centric, just not obviously so.

and now King Charles….

I love Borough Market - it is a must for me every trip to London.

All of London is owned by the monarch. That's why when you buy a property you only buy a lease.

Where do people get this nonsense from?
I met some Canadians is Spain last year who patiently explained why I don’t own my house in Cornwall because the Duke of Cornwall owns everything.

Absolute garbage.

So many great recommendations! Thank you for all the suggestions!
