Being in London was fascinating not only because I had never been there, but because we were able to see first hand where John had lived for the last two years.
The Gold State Coach at the Royal Mews. The tour of the Royal Mews was fascinating. This is where the royal coaches are kept. The one pictured below is used for coronations.
Big Ben, needless to say. :-)
Had no desire to go up in the London Eye, but it was lovely to see at night.
